Justin Nolan over at modiphone.net has released a workaround to enable most of the 1.1.3 $20 / £12.99 uprade apps on your iPod Touch. This is, in effect the file that you will have bought for $20/£12.99.
Have a jailbroken 1.1.3? The iPhone apps are locked away in the firmware. Install the App Enabler to unlock them:1. Add http://www.modiphone.net/repo to your Installer.app sources list. Refresh sources.
2. Install 1.1.3 Touch Apps under Modiphone.netPlease note that there is ZERO copyrighted code in this package. All we are doing is replacing the app’s Info.plist files with our own. Uninstalling will revert back to the default plists.
Note: MobileMail may or may not show up on your SpringBoard with this version. Please report back in the comments.
