After installing the jailbreak app "Winterboard" just now and then rebooting as required, all my apps including settings and phone etc. only display in top left quarter of screen.
Only that screen quarter accepts touch input, but the touches are relative to the entire screen. This means I can't interact with the bottom and right halves of any apps, making it impossible to revert the installation.
Googling for this problem tells me that it was a problem with the version iOS 5 GM, which is a pre-release. But I'm not using that; I've just installed the newly released iOS 5.0.1.
Also, the recommended fix is to use SBSettings to start in failsafe mode, but I never had SBSettings installed, and I can't install it now with the screen acting up this way.
How can I fix this problem, apart from restoring from my PC?
I know I can restore from backup and then re-do all the jailbreaking, but it'd be nice if there was a way to avoid that.
This is what I've done:
-
I first made a backup to my PC, then the iOS 5.0.1 upgrade, then a restore from the PC to make sure I had all the apps and data again (I didn't; somehow several apps were missing after the restore, but I just installed the rest manually).
-
After that, I did the jailbreak and started adding Cydia apps. One app required the installation of Winterboard, and that is what caused this problem.
-
I'm fairly sure Winterboard is the culprit because when it happened, I restored again, jailbroke again, and began reinstalling Cydia apps again in a different order. It broke like this again while installing a different Cydia app that also requires Winterboard.

There's a weird effect going on that indicates that although the size of the displayed image is reduced but the size of the touch area remains full-sized but unresponsive outside the displayed quarter of the screen. In a paint app, I can drag from inside the display quarter into outside, but I cannot start a touch outside the display quarter; nothing happens.
So I know that I can "fix" the problem by restoring from the PC again and avoiding any Cydia apps that require Winterboard. But I would like to avoid restoring if possible, to save myself the trouble. I'll keep that as a last option in case there's no other way to revert this.

He can't go to settings it's impossible the only way to fix is to restore everything and avoid winter board on ios 5.0.1 untetheted home screen is all that works after I went threw this once I found a cydia tweak app that can put my phone into safe mode and let me fix problem if it ever happens again since Im pretty sure u need winter board for sbsettings I can no longer use it for safe mode. Avoid winter board till there's a fix for ios 5.0.1 untethered.
