I've only owned the Samsung Infuse 4G (using ATT) for a few days, but it is truly an impressive device. I would strongly recommend it to anyone considering a top-line smart phone. Period.

My smart phone history is (recently) six Dell Streak 5s (which is an amazing device, but with a few flaws), a Blackberry Bold 9000, and temporarily (recently) an LG540.

Samsung Infuse is a beautiful phone. Vivid display (clearer and larger than any similar smart phone), logical functionality (16 Apps per page that scroll sideways), and the flexibility of Android.

It's capacitive touch screen works very well, and the onboard memory (and capacity to upgrade) is excellent.

The only weak point is the battery, but I've only had the device for days and it's not quite fair to criticize quite yet. However, having said that, it seems that if you allow all manner of back-ground programs to run (which is what will happen - unless you intervene), that you may spend some part of your day re-charging this device just to keep it alive.

However, experience users (e.g., ATT reps who own this device, & other US citizens) advise me that selecting Task Managers (installed) or Market-available task managers (free), will extend your battery's life well beyond default settings. Not sure yet, but it seems the battery will last the majority of the day IF you are not using Wifi, GPRS-web, running onboard programs to the max, and/or talking simultaneously throughout your day. Perhaps all that activity is unlikely, but it's possible.

Purchase a protective case immediately. This device is very thin, and its form-facter offers very little built-in impact-absorbing space (none), and you'll need to add some survivability to put your mind at ease.

I owned this phone for about a year with NO PROBLEMS. It is just that I change out phones often as I am a techie and have to have the latest phone/tablet, etc. And so I upgrade very often. However, the phone worked perfectly for the time I owned it, so here is my detailed review, and I hope that it will help you make a good decision if you need a great smartphone at this great price!
***Keep in mind that this Sim Unlocked phone will work fine in AT&T and even T-Mobile for calling and texting. But for Internet and MMS, you may need to set the APN settings. If you need the APN settings for At&T, T-Mobile etc, just ask me in the comments and I will send them.

Pros:

- Very clear and easy to read 4.5" screen.
- Outstanding colors and outstanding screen clarity.
- 2.2 Android allowed me to save many installed apps on my SD External card. (Cannot do this anymore after OS 3.0 and higher).
- Great camera - I took many high quality pictures.
- Wonderful music player app (the stock one was just right and makes great playlists,etc). Sound quality excellent.
- Got 4g on the Internet Data.
- WiFi came in clear and fast.
- Overall a easy to use and perfect size phone and comfortable to hold with big enough screen.

Cons:
- NO FM Radio. However, I installed Tune In Radio so if I had WiFi on, I could listen to all kinds of radio stations.
- Could use more memory, yet it still ran fast for me.
- It has OS of 2.2 Android, possibly 2.3. However, this is still a good OS and will run most Apps. I still have a Galaxy Player with 2.3 and all apps I installed run fine...

Good phone, after owning it for about a year, I upgraded to Samsung Galaxy Note N7000 with 5.3 screen.

I am an advanced user and have been using this phone since past 3 months. This phone has an amazing huge s-amoled display which blows away all other phone displays I have seen till date. I have owned Blackberry,Nokia,iphone,etc but this phone is the best of all. I purchased this unlocked phone and rooted it immediately and installed custom Zeus rom (Gingerbread). It removed all the AT&T bloatware and it can bump up its cpu speed from 1ghz to 1.6ghz with auto speed on demand setting as some graphic intensive games require higher processing power.
Phone is incredibly slim so you need to buy a good case to protect it plus a scratch screen guard. Battery drains out quickly as the screen is a monster power consumer and phone heats up very very fast with GPS and screen turned on for longer periods. The sound quality is superb, display is super good and its on par with iphone its slim body.
For advanced users like me, Iphone is really a piece of junk as I have customized each and every aspect of the phone which android allows and in my opinion, its far more advanced OS than anything in the mkt with tons of freeware available for downloads unlike paid apps from iphone. I am considering buying a second phone for my dad. At this price of under 350$, its a steal and it matches uptp 650$ dual core phones in the mkt with customized roms which can bump up the speed dramatically. It also has a state of the art GPU and phone is extremely fast inspite of loading it with so many apps. You can setup a wi-fi hub with your phone data connection too. Samsung is the worlds largest manufacturer of s-amoleds and other manufacturers have to buy from them to use it in their devices. Checkout xda developers site for installing custom roms on your androids ! Buy it.
