Why are jailbreak/native app developers still using .app format? Wouldn't it be better to use .ipa so we can have those apps stored in itunes? Think about it. This way when you install an app with cydia you can delete it the same way you do a legit app and it will sync with iTunes! Then when you restore or update you just sync it all back. All we need is an app that will modify the mobilinstalation for us just so we don't have people passing around the patched installation and app's converted to .ipa I think its time we switch standards. We could even go as far as changing the locations where themes and ROMs are stored so itunes backs them up when we sync!
