Help i7500 and AT&T

[Joeydroid]

I was going to buy an unlocked i7500 tonight from craigslist but when i put my at&t sim card in it recognized the sim but had no internet connection. The data icon had no 3g or E. When i opened the web browser it said No Connection. Didn't buy it

You must manually input correct APN settings in order for it to work.

Thats what i forgot to check Does ATT 3g work on the i7500 ?

Thanks
