I might get an iPhone (original) pretty soon, and want it on T-Mobile... Anyways, I was wondering: 1. Can I just walk into T-Mobile and have them activate my iPhone? (T-Zones hack and everything) Or I do have an old GSN phone, could they activate that, and I just move the sim into the iPhone? 2. Does T-Zones push email, work on youtube, and aim? My main purpose of it would be Safari, but it would be nice to have all that other stuff working as well. 3. This plan should be ok, correct: the $29.99 300 min talk plan plus T-Zones should work? 4. Anything else I should know?
