How to install an ipa file programmatically?

Can i still in stall cracked .ipa's on firmware 2.1 with the patched mobileinstallation ?

• the cracked mobileinstallation file isnt working i install it back up the other mobileinstallation and when i do this i attemp to reboot my iphone and when i do i get stuck in the bootlogo so is this a way that apple blocked cracked .ipa installation?

• Answer:

  Not yet .. the Mobileinstallation file is firmware dependent and has to be cracked in different ways. One way cracks it so non-apple apps will show and run from the springboard and the other way allows non-apple apps to run and ignores checking to make sure you are authorized to run the app. Just wait a few weeks and some moron will crack it both ways and you'll be all set.. By the way if you are reading this becuase you replaced the mobileinstallation file with an old version and your phone gets stuck with the boot logo. Simply dowload the iphone/itouch diskaid and replace the file. Even though your phone is stuck it is still operable in the background. After you replace the file wait about a minute, the phone should startup without a restart.
