Not true, all carriers lock their devices to their network with a $250 charge to remove the subsidized lock, TMo being the exception (If your in good standing and have been with them for a period of time) Otherwise consult Bongo Wireless www.bongowireless.com
and no there is no other option for unlocking. Kindly search next time as their are hundreds of threads discussing this topic already.

At least that has been my experience with getting ATT/Cingular, Rogers, 02, Vodafone, etc Blackberrys to work on the T-Mobile network with email. But I guess it helps that I work for T-Mobile?
