So I upgraded my jailbroken 3Gs to the 4.0 and had some issues. My 3G wouldn't work. I found out that I should restore as new phone instead of from backup and that fixed the issue (lost all my apps etc tho). Now I find that my favorite JB app ProSwitcher doesn't seem to work with 4.0. Springboard keeps crashing. Any fixes for this? I can't live without ProSwitcher. I wish I never updated.
