I was paying 107.00 per month at&t (iphone, 900 minutes, 200 text messages, unlimited data).
after my iphone went bad and stopped working with no help from at&t - phone is 18 months old and warranty was only one year, i bought a blackberry from ebay and lowered to 450 minutes, unlimited data, 200 text messages and now my bill is 80.00 per month.
i thought about sprint and vzw, i used a droid at vzw's store and it was fast on their network.
made my iphone look like a slug in this area. i had seen some really quick 3G service from at&t in Nashville, tn when the hotel we were in had a failed wifi system. I had to resort to my phone for web. my laptop would not get any open wifi signals down there.
3G here is not much to brag about imo. i can't tell much difference from edge except the symbol on the screen changes to 3G.
