iPhone 3GS Slow After 3.0 => 3.1.2 Upgrade
I held off on upgrading from 3.0 as long as possible as I did not want to go through the JB process.
Last week I decided to make the junk to 3.1.2 and since then, the phone has been VERY slow. It takes about 20 seconds for the alarm clock to show, the calendar will not load, and everything else drags. The phone is JB but it was this way before I applied the JB.
I have not installed any new programs that were not on the 3.0 OS. I have tried all restore methods. The problem is that iPhone wants me to upgrade to 3.1.3. That may be a solution, but I will lose JB - right?
I tried a workaround method to downgrade back to 3.0 but the restore process fails after it extracts the 3.0 OS from its file on my computer.
Any suggestions? Thank you in advance.
