If anyone is wondering how to unlock Motorola iDen phones and make them
work on other providers like Boost mobile, SouthernLINC Wireless,
Telus, Mike, XPress, MiRS
follow the link below we do the remote unlocking for a small fee, no
special cable is required, it can be done with the original USB cable
that came with the phone.
