i recently just ditched my iphone 3gs in favor of the nexus one with at&t 3g. my concern is, i logged into my at&t account online and at&t does not recognize the n1, which i figured it wouldnt, instead it has my phone listed as some non-smartphone, however my monthly plan remained the same and still has me listed under the iphone data plan with no option to change to a universal smartphone plan..i realize the iphone data plan and the universal smartphone plan are both $30/mo, however i would just like to make sure i wont be charged data usage per kb used, since im not actually using an iphone anymore. has anyone else coming from an iphone noticed this? was anyone else able to select a universal unlimited smartphone plan?
