I have wifi problems with 5.0.1 so i decided to go back to 5.0, i had saved the SSH blobs before updating to 5.0.1 so i used iFaith 1.4 to build custom ipa for 5.0 and then resore it via iTunes. Then i used redsn0w version 0.9.10b3 to jailbreak but it shows as tethered jailbreak and the Cydia icon is blank and wont open, i tried booting just tethered with redsn0w and it is a tethered jailbreak, what shall i do?
