trying this method (make sure itunes is not running in the whole process)
1. open redsn0w
2. select ipsw and direct to ios 6 (not ios 6.0.1)
3. after redsn0w is ready for jailbreak select downgrade from ipad baseband (if you need to install cydia select that as well)t
4. after jailbreak is complete, close redsn0w and plug out your iphone
5. restart your pc/mac
6. open itunes and connect your iphone. It should work
enjoy :)
