Totally worth it! I dont know why people drive in sheep to put an at&t or verizon sim in their ipad when you can just buy the "at&t version" and put a tmobile sim in it and have UNLIMITED data on it. FYI all ipads are sold unlocked. Dont get stuck into thinking that it's an "at&T ipad". Its just branding.
T-Mobile's towers have been refarmed to support iphone and ipad and there is no reason to put it on at&t. I have had Tmobile since the past month for my ipad and it has been working GREAT! I average 12mbs with HSPA+ in NYC.. Once Tmobile rolls out LTE in 2013 it will reach 50mbs. BUt 12mbs is plenty enough, its like cable connection
