i have Tmobile service with data plan. but after JB and unlock, for some reason, my 3Gs doesn't connect with the data plan. instead it tells me that i do not have a data plan available 
i'm on the 3.0 FW. is there anything i need to add like the APN or something like that in order for it to work?
thanks!
