Service book issues.
Did those issues every get resolved for bis 8300 users using unlocked bbs?
Or are you all still having problems? Just curious, not liking the reception i'm getting on att and thinking of switching.

O2 curve unlocked on Tmo. Absolutely NO issues. Also have a ATT curve on ATT - slower operating system and more memory eating crap. Not as stable throwing a couple of exceptions a week. Love the O2 curve and service signal on Tmo is better than my ATT in NYC and Bronx.
