Fix problems after 1.1.3 Jailbreak

From IpodTouchFans

1. Go to the Sources tab in Installer, tap Edit in the upper-right hand corner, then Add in the upper-left
2. When prompted to do so, type ihacks.us/index.xml, so the whole line should look like the following: http://ihacks.us/index.xml
3. Refresh your Sources (it should probably do this automatically)
4. Once sources have been refreshed go to Install > AlliPodHacks Software > Fix Jailbreak Symlinks 1
5. Respring (should happen when you quit Installer) and enjoy!
