All you do is this:
1.SSH into your iPhone and go to System/Library/Coreservices
2. Copy M68AP.plist
3. Open that file in a .plist editor
4. Make a new child under the compatabilites dictionary called video-recorder then set it to BOOLEAN Then check it or Type "True"
5. Re insert file into phone overwrite old one.
6. Respring or reboot iphone and click camera application
7. Video RECORDING DOES NOT WORK YET But you can see the switch
Maybe it might be in a next update ;3
P.S. you can enable numeric battery into the iPhone by inserting into that m68ap plist file gas-gauge-battery and set it to boolean and make it True or check it. then enable it under settings!
If this helped you please thank me
Good luck.
