I do I check of my iPhone thats unactivated has bootloader 3.9 or 4.6?
It was bought a while back.
There is an app called BBinfo that you can run on your phone and it will tell you what baseband you have.
For 8gb iPhone, if 4 and 5th digit of serial is less than 45 it's typically 3.9, 45 or higher than it's 4.6.
All 16gb comes with 4.6 I think.
