I signed up with ATT in March with hesitation due to the bad things I have heard about dropped calls, etc in the NYC area. Overall voice calls have been great, both in lack of dropped calls and sound quality. My gripe is data. I have an iPhone which I absolutely love and its the reason I came over to ATT. But, the problem is from around Pm-Pm data is so slow or at times even unavailable (it drops the G indicator). Before or after that time, I get great speed, around 1500-2000 on downloads. During these peak times, I am lucky to get 200.
