I have an iphone 4 with following specifications:
Baseband : 2.10.04
iOs : 4.1 (8B117)
Status: Jailbroken but Locked (using Gevey Sim to unlock it)
SHSH blobs : saved for 4.3.3, 4.3.5, 5.0.1, 5.1
I tried to upgrade it using RedSnow 0.9.14b2 using iClarified tutorial to upgrade to 5.1 without updating your baseband.
I successfully created custom ipsw. But when I try to restore it using iTunes(10.7), It gave error 3194. I changed the hosts file to redirect it to the cydia servers. Then tried again. Now it gives error 1600.
Now I have few questions:
Can I upgrade it to ios 5.1 or 5.1.1 in anyway?
Will I be able to use Gevey Sim with ios 5.1 or 5.1.1?
