I know you can make games for both iPhone and iTouch but can you use unity3d with a iTouch or does it have to be an iPhone in order to work with the computer for editing the game?
Both work fine. Just keep in mind that for testing purposes the 4 available models vary in performance from fastest to slowest as follows:
iTouch 2nd Gen
iPhone 3G
iPhone 1st Gen
iTouch 1st Gen
ok thanks
