My guess is that it will probably have the same problem that the Samsung i760 had when trying to enable WAP. There's probably going to be no way to make data connectivity permanent. Being CDMA, it will have to have some Qalcomm chipset in it for the radio. More than likely, it will have some areas of memory that handle the same non-volatile memory spaces for the PRL, NAM, security, etc.
I'm fairly certain that a basic flash (voice and text) won't take long. But I think full data and MMS will be the rub. Just my 2 cents.
