Solution: unmount winterboard !!!
Touch2 tried to crack ios4 last night.
Http://www.jailbreakme.com/
The third part implements online cracking and is installed
PZ, taptapant, winterboard and other software
Problem:
1. PZ cannot be opened. Later I checked the log and found that the new version of PZ could not be opened with itouch, reporting that the device loading failed (touch is not a phone after all, but a few fewer parts nnd ), removed the old version!
2. The taptapant cannot be opened, and there is no record in the log. At that time, the first reaction was the software conflict (unexpected inspiration ^_^). It was tested.
Talking about the winterboard stuff, since the installation of the entire touch feels twice slower, after the removal of this program, the program runs normally, the machine speed is also significantly improved :)..
I don't know if this is not a case. Leave a background first. After all, the solution process is crazy. No logs are displayed. I can only guess (I have installed more than 80 software ), I hope this will help you with this problem !!
