 If you are a developer with an official apple code signing identity you can deploy Kodi
 via xcode to work on it on non-jailbroken devices. For this to happen you just need to alter the
-Xcode project by setting your codesign identity. Be sure to not just select the "iPhone Developer" shortcut
-but instead select your full identity "iPhone Developer: your name (your id)" (this is important else our sign
-script won't detect a real sign identity). Its also important that you select the signing on all 4 spots
+Xcode project by setting your codesign identity. Just select the "iPhone Developer" shortcut. 
+Its also important that you select the signing on all 4 spots
 in the project settings. After that the last buildstep in our support script
 will do a full sign of all binaries and the bundle with the given identity (all *.viz, *.pvr, *.so files
 Xcode doesn't know anything about). This should allow you to deploy Kodi to all non-jailbroken devices
 which you can deploy normal apps to. In that case (Kodi will be sandboxed like any other app) - all Kodi
 files are then located in the sandboxed "Documents" folder and can be easily accessed via iTunes file
 sharing.
 Keep in mind that no hardware acceleration will be possible without jailbreaking when using iOS < Version 8.

+From Xcode7 on - this approach is also available for non paying app developers (apple allows self signing from now on)
