Need help for backing up apps
I recently got my iPad and on the first day I synced it on my friends computer.. He was using his iTunes account and had all his apps purchased from app store.. Now when I was going through the apps i realised that it took up most of the space and i want to clear out abit.. but before i do anything i want to create a backup on my computer.. is it possible to put all those apps on my computer without losing any data(without syncing)??? Plzz help.. I would really appreciate it.. :)
Note: I synced only the apps and not any media or any other data..
Thanks a ton
