I bought this for my wife as a replacement to a troublesome Nokia. I was worried after reading recent reviews about it not being unlocked. Thankfully I had no problem and phone works well on a T-Mobile network. Before using the phone I updated all the software for the phone. This took at least 90 minutes. It updated to Windows 7.5. I had to also install Zune software on my PC in order to update the phone and copy over music and photos.
We have T-Mobile and the phone is set up for ATT. It is annoying that the ATT options are still on the menu. Can't get rid of them. I was surprised by the weight of the phone, a lot heavier than an i-phone, but then it cost 75% less.
My wife uses the text option the most, so the slide-out keyboard is a very handy option.
So far this phone is working great.

LG Quantum C900 Unlocked Phone with Windows 7, QWERTY Keyboard and 5 MP Camera - Unlocked Phone - US Warranty - BlackWhat a dissapointment and a waste of time and money! Phone was locked although it was advertised as an unlocked phone. No success getting any assistance from vendor, OEM Planet! Absolutely no customer service. In addition, they blamed Amazon who in turn blamed OEM Planet for sending a locked phone. No assistance from Amazon either. Got the unlocked code from ATT and the directions did not match the prompt from the LG phone. Instead of asking for the unlock code, I asked for the PUK code. Apparently, if you entered the wrong number 5 times, the phone is permanently locked for ATT. What a shame because although I had the unlocked code, I could not unlock it. Maybe the phone was already returned from another customer and I was given a second hand phone? In any case, I am the victim of fasle advertisement - this phone is NOT unlocked. Shame on Amazon and OEM Planet for providing the wrong item to customers and not resolving this issue in a acceptable manner - apparently, I am not the first one and the product is still in the market. Do yourself a favor, do not purchase from OEM Planet. I would have hoped that Amazon would have done the right thing and investigate other's claims and remove that item from their website. This would have avoided others to have such a bad experience.

Moving up from an HTC TyTN II, this Quantum C900 is all I could ask for: thiner, larger, faster, sharper, easier to use and fancier! Just by turning it on I noticed what a big difference it was.
The OS is quite friendly and powerful. Company's Exchange Server sync was perfect since the the start. So far I have no complains regarding Windowsphone. I have not updated it to Windowsphone 7.5 yet, but honestly, do not feel the need to do it...although I will certainly upgrade it. There are not as many Apps at Microsoft's Marketplace as Apple has for the iPhones or iPads: theirs have been around longer..but I was able to get most of what I wanted for free. Other bright side: Apps price is quite low compared to what I have paid before for Palm or even Windows Mobile programs. Hopefuly in a few months I will get the Apps I am now missing.
Hardware wise the phone seems very well built: it feels heavy and sturdy; also fewer moving parts will probably mean less problems down the road. The only thing I do not like is that the phone is an AT&T unlocked phone, not an LG OEM phone: BIG difference when it comes to support: LG will not handle it and neither will AT&T if you are not with them. The seller probably has a warranty agreement with ONE shop...but that certainly limits your options.
Bottom line: Excelent value for money. Would be great if it wasn't an AT&T phone.

I Love This Phone So Much, I Forewent a 4G Phone To Get Another one.
I dropped my first LFG Quantum, cracking the screen. Even then, it soldiered on, but developed a tendency to occasionally reboot after sliding the keyboard closed. Read more
