I don't know if its already there as i could not find it.
There should be a feature using which I can track my uploads
I mean it ll keep an eye on Itunes versions for my uploads and ll let me know is a new version is available on iTune Store. I ll re-download the latest version and crack it for AA.
Reason why :-
I am not using all the application that i cracked on my iDevice (So there should b a way that i can know if the new version is available). Of course I can update them here as they are under my purchases in iTune Store.
Current Tracking system is tracking AA versions only.
