For some the new BlackRa1n jailbreak was causing problems with wifi, youtube, and push. Here is a quick guide on how to fix these problems.
WiFi
1. Go to settings, general, reset, reset network settings then click ok
2. Reboot your iPhone, when it comes back on wifi should be fixed, but next time you reboot you have to do this again (if your doing the next fix don't reboot yet)
Youtube and Push
1. Go to cydia
2. Tap Manage at the bottom
3. Tap Sources
4. Tap edit in the right hand corner
5. Tap add.
6. Type cydia.iphoneneil.com
7. Tap done
8. Search PushFix and tap the first result
9. Install then confirm
10. Reboot your iPhone.
