Updated from 1.02 to 1.1.2, 4.02.13_G.
Followed the guide, but activation on page 2 does not work. When I put in #307# and press Call, it doesn't ring.
Any suggestions?
Actually, I couldn't check the SIM PIN after downgrading to 1.1.1 (stuck in restore mode).
I am on AT&T, so no need for or history of unlock with my iPhone.
When I put my iPhone back to 1.1.2, the PIN is off, Is that the default with my AT&T SIM for 1.1.1 as well? Did I miss something here?
I really need a solution for OSX that works, and if this is it, I would appreciate someone letting me know what I might be doing wrong.
