T-Mobile Wing, HELP! HELP!

[ChOpCbR1332]

The t-mobile wing is not letting me install the RegEditor program i have, I also have a Sprint Mogul, Which doesnt not require a Sim card(Thank God), but do I need to unlock the Sim card or something, After I place the Cabs on, Through active sync. It says unsuccessful and deletes the cab or any file off my phone.
thanks I would really appreciate it.
