I am against piracy and will never support it. iPhone OS 3 users face the problem of not being able to install applications that require iOS 4 or higher. This little project by me is a decent solution: users can finally find most of the apps they need working and tested by me.
The search bar (by Google) could provide non-free cracked apps. Please do not abuse this service because it damages the developers who are not to blame for Apple's marketing choices which require the submission of applications with iOS 4+ compatibility, only in the Official App Store. So please buy apps from iTunes on your computer first and only after then use this service to put in your device an iOS 3 compatible vesion of that application.
