Expert's advice required, thx. Am using my 3g 16GB when the v2.2.1 was released, upgraded it to v3.0 long time back, JB & unlocked it all by my self.
Now i am feeling the urge to restore my iPhone, so to fix speed issues.
I am planning to upgrade my 3G V3.0(7A341) FW 04.26.08 to V3.1.2.
So shall i go ahead with it? I have already downloaded the FW V3.1.2 from apple official site, and will be restoring it with the new FW using shift Restore button.
Then i will be using blackra1n to JB & blacksn0w to unlock.
Please correct me if i am wrong in some point.
Thanks & regards. |
