I am new to CDMA. I have a lot of experience with my GSM Touch (Elf) but I think it is something different between falshing a GSM Touch and CDMA Touch.
Like if I flash my CDMA touch, will my phone number gone? How can I just flash a new ROM without lost my carrier and phone number? What should I do to start flash my CDMA touch? Is it after flashing a custom ROM I could release the internal GPS?
I am in New Zealand and service provider is Telecom. Please pointing me the way to go. Thanks
