I have many complaints about ScreenSplitr 3.0 not quitting on firmware 2.2. Since I don’t have a 2.2 iphone anymore I had to borrow K. 3G which was still running 2.2.1. I asked her to do a simple backup but before I knew it, she happily agreed to please iTunes and upgrade her iphone to the latest! Nice. Stuck with a 2G and a 3G running 3.0. After 2 hours of screwing around, I was able to downgrade it back to 2.2.1. Unfortunately now it has the 3.0 baseband update, so I hope I can still jailbreak it with ultrasn0w.
In any case, after more time trying to build and run ScreenSplitr 3.0 on the 2.2.1, I found out that on 2.2.1 if the app terminates while resuming, the OS happily restarts it because it thinks that it was resuming while it was terminating and that what the user wanted was really to restart it! This doesn’t happen on 3.0 of course.
The fix is to delay the suspension on resume by 2 secs. phew
I have informed BigBoss of the fix. Now we have to wait for it to be published. Look for version 1.1.0-16 on cydia.
Now back to upgrading 3G 2.2.1 to 3.0 and jailbreak/unlock it.
