Just a summary of what I've been through and noticed.

I've had no data and dropped calls/20-30 of dropped voice starting around 11am - maybe 4pm consistantly for the past few months.

I've contacted AT&T and had multiple cases opened.  They come back "solved" without even verifying with me.

In the past I've had my phone replaced twice, sim card replaced, been through tech support dozens of times, and I'm getting nowhere.  It HAS to be something with their tower.  When tech support runs out of ideas they tell me that I must be out of the signal's range... well I have 3-4 bars and it tells me I have a 3G connection... So why are my calls and data not working????

I've had more issues with AT&T in a day than with Sprint or Verizon over the past several years.  Sad...
