AT&T can tell whatever phone u are using on their network. I'm not sure of the specifics but this wasn't always true. It used to be customer info for phone type was only thE last imei changed (new phone, upgrade, customer called it in) but now (maybe it's only 3g) whenever u swap phones it switches in their system. That explains customer being on a mediamax plan with the iPhone would receive the message "you're not an iPhone 3G data plan, blah blah blah". It's true for most phones (I swapped my sim with my old Sony Ericsson z500a and logged into my account and showed up as my device. Then I put my iPhone sim card back and a little while later it switched when I logged back into my accout. Give it a try
I don't know when it started but IM gonna have trouble keeping my plan now
