i am looking at getting the t-mobile mytouch 3g, i was hoping i could get some questions answered here from those that know. 1. what is the difference between the 3g(with 3.mm jack) and the 3g slide (other than the slide out keyboard)? 2. what version of android is the 3g running? 3. does the 3g have led notification light, or does the trackball light up? 4. how is the 3g as a phone, call quality on each end?? 5. how is the speaker/spealer phone? very important!! 6. in general how is the battery life for light users, say a couple calls, couple texts a day, light web surfing? 7. any negatives that would make this phone a deal breaker? i am looking at this phone because of a few things. i like the size, it does not seem so huge as the droid x or evo. i find i really need a trackball when using the web. i have studied the vibrant and it seems awesome it is just missing a few things. i also do not like slide out keyboards, they bother me and make the phone to heavy, any help will be appreciated, thanks!!!
