Just bought a 6310i off the web. Wireless Ruler.com via Yahoo Shopping. That was my second attempt. The first dealer could not find one (and actually charged me and then had to cancel the charge). Several of the AT&T stores indicated that they are out of stock and did not know when they would get more. Also, AT&T would not sell unlocked nor provide a code to unlock vis. T-Mobile.
So far so good. Better features and lighter than my old Nokia 6310. I have had good reception on the phone thus far, despite warnings about AT&T's GSM network still being underdeveloped.
I haven't managed to get my CLIE TG50 fully working with it yet as far as being able to browse the net. I will need to get have a dial up ISP. Anyone know of a cheap and reliable one?
