Hello, i just purchased a android device today from my iphone 4. The guy at bestbuy wasnt the brightest while setting it up and getting it on my plan. But its all working fine. I only have a couple questions though, When i log into my AT&T account it still shows that i have a 2gb data plan for iphone. And i am unable to change this to 4g data plan for my android 4g device. is this something i have to call them about? Also, when i had my iphone 3gs i had an unlimited data plan, what happened to this? I thought i would keep it as long as i had my contract paid.
