Is there a Need 4 Jailbreak when SDK for ipod touch released

The SDK will be used by developers to make software for the touch that will be downloaded through iTunes (most likely) and will be for a certain fee...but these apps will be Apple supported and iPod safe with little chance of breaking your iPod down.

So if you jailbreak, you have a risk. If you don't and use the iTunes route, you have to pay more but it may well be worth it.

Some developers may make Apps for free, like Google or AOL
