Does anyone know if the T-Mobile version (like the one being sold on Amazon) will work with an iWireless account? iWireless is a subsidiary of T-Mobile and uses their network. Would I have to get the Tab unlocked to use it on iWireless, or should it just work? I know for some T-Mobile phones, the service just works, while others you have to unlock the device. Does anyone know for sure? Thanks!
