i have this phone, it is great, my fist one had issues with shutting down, did a warranty exchange, current phone is great, except for few bugs/issues like
1) dust accumulating in front facing camera, i don't use front facing camera much.
2) some issues with Bluetooth, if i connect a Bluetooth headset, then connect headset with audio jack, songs play fine on head set but when i switch from audio jack to Bluetooth (after disconnecting audio jack) the song plays fine on phone but cant hear on my Bluetooth headset.
3) Camera is great for videos, good pictures in dark, OK pictures in daylight, especially portraits.
4) great GPS, option to download maps is awesome feature, can use GPS when there is no signal.
5) awesome screen, great battery life too, depending on how you use it.
6) not great in managing background applications, i did set my FB to run in background but it doesn't, it says next time when i use this app this should run in the back ground, i tried to start the app go back & see the settings it is not running.
I have not found one problem other then a lack of apps and some possible camera improvements via software. This is the best phone I have ever owned I even rate it better then any iPhone I've owned. Its got some software enhancements needed but for 99 bucks? Its the best deal I've ever received.
