I gave my son in law my ppc6700. The unit has been previously registered by me (before I got a Mogul) on Sprint. The unit was probably initially registered when it had OEM WM5, but in the end it had been upgraded to custom WM6.
My son in law is having difficulty in getting the phone registered with Sprint. Is this because Sprint recognizes that a custom ROM is installed and will not alow the phone to be put on the system? If so, does he just need to flash back to a standard ROM for registration and then upgrade to a custom ROM with ICS?
