Came from AT&T, had the BB bold
Loved the keyboard, BBM, Email
Hated the trackball(liked at first)
battery issues- would show as being charged full, but would die a hour later
had a lot of problems with last ATT OTA upgrade to the current operating system
And I really hated the fact i was paying 126 dollars a month for a smart phone that did not seem to smart. I thought i would have to pay a ETF for leaving ATT, but they never charged me.
I am glad I switched to the EVO, 2 of my Roommates had them and i was hooked after seeing what it could do for a lot less then what I was paying per month. Rooted it, and switched roms, and im a rom addict now. lol
