[WARNING] Don't install ASprefFIX 1.1.3 (DEV soft upgrade)
If you have soft upgraded to 1.1.3 with dev-team solution, don't install ASprefFIX 1.1.3 from sendowski's sources!!!
After deinstalling it will crash your network settings and therefore your wifi connection.
At the moment, the only solution is to go back to 1.1.1 and restart with the jailbreak cycle meaning:
1.1.3 no wifi --> restore 1.1.1 --> jailbreak --> upgrade 1.1.2 --> jailbreak --> soft upgrade 1.1.3
Before you do that, backup your iPhone! Otherwise your data will be lost 4ever.
Forgot how to do that?
