how does it work? do those beta testing need a jailbroken ipod or is it something that you do through itunes or what?
the dev needs testers to test their games for bugs and such. they give their testers a special version that the devs assign to an idevice using its UDID. then the dev gives the testers the download via a the internet and they put it on their ipod. it kinda weird but its cool to beta test.
