Product Description

It runs on the 850/900/1800/1900 MHz GSM/GPRS/EDGE frequencies as well as AT&T's dual-band network (850/1900 MHz; HSPA/UMTS) plus international networks (2100 MHz).

Designed for work, play, and everything in between, the LG Quantum is one of the world's first smartphones using the Windows Phone 7 operating system. It gives you the productivity of Office Mobile and Bing, plus the fun of Xbox LIVE and Zune. With a slide-out keyboard for quick use of Office Mobile, you can stay active and up to date with work. The LG Quantum also features DLNA technology through a preloaded application called "Play To," which allows you to wirelessly stream videos, music, and pictures from the phone to a DLNA-enabled TV, stereo, Windows 7 PC, and other consumer electronics devices.

The LG Quantum includes a 3.5-inch touchscreen and slide-out full QWERTY keyboard (see larger image.)

Enabled for use on AT&T's lightning quick HSPA network, you'll be able to easily access the Internet as well as quickly download video, music and more. Additionally, with AT&T's network, you can make a call while simultaneously receiving picture/text messages and e-mail, or viewing Web pages. This GPS-enabled phone can access the AT&T Navigator service for turn-by-turn directions as well as its Video Share service, which enables you to send video of yourself to another compatible phone while making a voice call. See more details on optional AT&T services below.

The Power of Windows Phone 7

The Windows Phone 7 operating system has been carefully crafted to help you get more done in fewer steps with a unique Hub and Tile interface. Instead of the common icon displays on the screen, Windows Phone 7 uses Live Tiles, which allow you to find out what's going on, what's happening next, and what you've missed without having to open an application.

Hubs bring together a related set of applications, services, and content in a single view to simplify common tasks. Your contacts, music, games, and work can be shared, synced, and accessed virtually wherever you happen to be. Windows Phone 7 also integrates with many popular Microsoft services such as Xbox LIVE, Windows Live, Bing, and Zune.

Live Tiles on the start screen dynamically update, so there is no need to open an app, and you decide which Tiles you want and where you want them. The Start screen includes the People Hub, which constantly refreshes with status updates from your favorite friends. The Me Tile lets you update all your social media sites, like Facebook--just type once and post everywhere with ease. Other Tiles allow you to quickly see new e-mails arrive in your inbox, play games via Xbox LIVE, and access recent photos and albums to view as well share with others. Swipe up to view more Tiles like music, Office, and more.

In addition to Internet Explorer 8 for full HTML Web browsing, the LG Quantum also includes fully integrated Microsoft Exchange e-mail and calendar as well as the Office Hub, which offers mobile versions of popular productivity programs, including Microsoft Word, Microsoft Excel, Microsoft PowerPoint, Microsoft OneNote Mobile, and SharePoint Workspace Mobile.

With Windows Phone 7 you can stay on top of your inbox and quickly cut through the clutter to see only unread, urgent, or flagged messages. Move or delete messages in bulk, and respond to meeting invites right from your inbox with Outlook Mobile. Streamlined account setup works with Windows Live, Google, Yahoo!, and other popular providers. Windows Phone 7 also combines your work and personal calendars in a single, color-coded view, making it easier to spot conflicts and manage your life.

Microsoft Office Mobile is another reason you won't miss your PC when you're away from your desk. Windows Phone 7 has mobile versions of Word, Excel, and PowerPoint on hand for reviewing or editing on the go. Notes in OneNote Mobile--grocery lists, meeting memos, spontaneous musings--can sync wirelessly to the Web and include voice clips and pictures. SharePoint Workspace Mobile makes it easier to collaborate with your coworkers when you're out and about.

You'll also be able to personalize your phone with the Marketplace Hub. Read reviews, check out ratings, and test out content before you buy.

Windows Phone 7 is designed for business and life in motion (see larger image).

Entertainment To Go

With the LG Quantum, you can access your favorite music and games thanks to Windows Phone 7's tight integration with Microsoft entertainment services:

  • Xbox LIVE unlocks a world of games and fun, connecting you to a global community of more than 25 million active Xbox LIVE members and offering easy access to Xbox LIVE features such as Friends, Avatars, Achievements, Messaging, and more (learn more below).
  • Zune for loading your favorite media--music, movies, TV shows, and podcasts--and taking it wherever. With a Zune Pass subscription, stream millions of songs right to your phone--no need for extra memory.

Additionally, each new Windows Phone from AT&T will include AT&T U-verse Mobile, an app that allows you to download and watch hit shows on your smartphone. U-verse TV subscribers with certain packages will be able to download and watch hit TV shows for no extra charge, and all U-verse TV customers can also schedule and manage their DVR recordings from the app. For the first time, U-verse Mobile will be available nationwide--even to those who are not U-verse TV customers--for just $9.99 per month. Subscribers can access the full content library, select which series or specific episode to download over Wi-Fi, and view on the go wherever they have their Windows Phone.

By Andrew D. Lossing VINE VOICE on November 21, 2010
Windows Phone 7 came along with just enough fanfare to catch people's attention. Even with the ill-fated Kin on their recent record, Microsoft managed to raise some excitement and anticipation for their latest foray into handheld computing. And this time, it met and exceeded all expectations.

There were several smart things Microsoft did with Windows Phone. One, they moved as far away from Windows Mobile 6.5 as possible. Windows Phone is a new breed, and has none of the ponderous weight of that operating system. Next, they satisfied their small but loyal handheld fanbase by, essentially, creating the Zune Phone we asked for. Also, they managed to cleverly elude all of the (ignorant) ridicule the Zune brand of electronics has endured by not labeling the device as such. But, as those who've played with the amazingly simple and sexy interface of the Zune HD recognize, this phone's workings are essentially the same, albeit matured and expanded upon. Then, Microsoft successfully implemented what is arguably their best project aside from the computer OS, Xbox Live. Another sure way to gain followers, putting some of the Xbox 360 experience in our pockets, at last!

The other elements of Windows Phone are equally impressive. A mobile version of Office comes with the phone. Whatever your preferred email provider is, it'll interface fully with the phone (I use Gmail). Responsiveness and reliability are a joy. Every aspect of the phone shows careful attention to detail, a great sense of artistry, and a mature understanding of what a mobile device should be.

I went into an AT&T store to check out the available hardware.

I've had the LG Quantum for 5 days now and I really like it. I moved from an iPhone and don't regret it at all. One of my favorite features is the ability to wirelessly sync your music and pictures to and from the phone. Even better, when you are syncing you can still use most of the phones functions, with the exception of marketplace and zune, unlike the iPhone.

I admit that there are still a few flaws in the system which some people may find irritating. First, landscape mode isn't quite solid throughout the OS yet, which is sometimes irritating with the Quantum. Also, we have to wait another month or two for copy and paste and (hopefully) custom ringtones. Neither of these were deal breakers for me because Microsoft has acknowledged their absence and that they will be changing these features, unlike certain other companies who are never wrong. I have some problems using WiFi occasionally and don't know why. A specific complaint for the Quantum is the Shift and Fn keys. I would have preferred one of those to replace the ae key which is used very rarely by most people in the States. However, it's not a deal breaker and you will get used to it very quickly. The volume rocker could stick out a little further, along with the camera button, but these are also easy to get used to.

Positives: The screen is great. I was initially concerned because it doesn't look as nice as the Focus in stores, but the screen looks great on every setting. The live tiles are fun and make using your phone take less time in some circumstances. The people hub is fun and I'm happy we have the ability to only see people in our contacts list. The keyboard is great. I'm a guy with average sized hands/fingers and have few problems with it.

I have had a Samsung Blackjack II for about 3 years and have looked with envy at my kids iPod Touch devices and it didn't help that I got my wife an iPad for Christmas. Time for Dad to get a new toy!

Anyways, I researched this to death and read / saw / handled most of the following: iPhone 4, Samsung Captivate, Samsung Focus, Blackberry Torch, and of course, the LG Quantum. What I found is, there is NO "perfect" phone for everyone so take my review for what it is, given that I am a tech marketing manager who:

- Reads / writes maybe 20 or 30 e-mails per day on his phone for each his company Outlook and Yahoo personal e-mail accounts.
- Enjoys the occasional game (free!)
- But mostly the apps I use most are weather, stocks, and sports news / scores.
- OK, YouTube, Facebook and Netflix are also nice to haves

With the mobile phone industry moving so fast, I was wary of plunking down even $150-200 for one of the phones listed above (2 year ATT renewal price). I was enticed by a $49 offer for the Torch, but my IT guys say we have problems occasionally activating phones for Blackberry's messaging service, and I am too comfortable with ActiveSync / Outlook to risk problems with sync. Also Blackberry seems just a step behind on latest hardware / GUI design: no one raves about the slower chip on the Torch, or the new browser, compared to the other phones. So I waited... and ALMOST pulled the trigger on $199 for the iPhone 4. Go with #1 right?

Well I guess ATT wanted to really push WP 7 phones, so the promo dropped the price to $49. Having been a fan of the LG Focus's keyboard and the VERY solid feel of the device when I handled it, I figured you really can't go wrong for $49.
