I made the switch to a Windows Phone and went from 3-10 dropped calls a day to 1 in the past week --still on ATT. I can make calls in more places too. Seriously I didn't expect this. The helpful folks at the Apple store always pointed to ATT when I asked about dropped calls. I just think that this comparison can help get Apple to stage one - accept the problem -and move to stage two - fix the problem (not point the finger at ATT for the total blame.). I would like my personal iPhone to work better.
