ok so i have AT&T and im looking for a phone online and i found a really good deal for a sidekick. i know that you need to have Tmobile because you need the "smart access" plan or something for emails and internet or stuff..but can i still buy this phone, keep it on AT&T, and just not have email and internet and stuff? just texting and calls and stuff? any othe rinfo is appreaciated.

thanks so much in advance.
