I updated to 1.1.3 and bought the app pack from itune. 1 day after I downgraded to 1.1.1 and JB to 1.1.2. then I updated again to 1.1.3 on another computer. On the new computer I was asked to pay again if I wanted to have the app pack. I just activate my itune account on the new computer and created a folder called Mobile Applications in the hidden file where is itune (documents and settings/..../application data/apple computer/itunes/) and I pasted the iPod touch App Pack 4A93.ipa file into it. restart itune and sync the ipod and I have the app pack installed. The only limitation is that you can only activate 5 computer with one itune account. So if you have 4 friends dying of trying the 1.1.3 with app pack this is one way while waiting for the complete jailbreak. Of course I think you need the ipa file that correspond to the itune account.
