So i have successfully upgraded to 3.0 using redsn0w.
The problem is at times, my networks isnt getting recognised.I can make phone calls but people cannot call me. I tried it with my telephone at home and it didnt work
This is iPhone 2G running 3.0 and im pretty sure i did the jailbreaking process alright.I clicked unlocked and successfully added the bootloaders.I even used bootneuters but it didnt work.
