Hello all,
I know this has probably been beat dead but i want to be very sure before I GOOF IT UP.
I just bought a used Cingular branded, unlocked 650 with Firmware 01.31 and Software 1.15-CNG. I loaded the software and got it up and running ( I even have full internet going with T-Mo) I would like to dump all the Cingular software and install the unbranded software. Can I just install it over what I have, or should i leave well enough alone? Also which versions should i use?

Thanks
