Mine too. I highly highly doubt they're going to allow full access to everything.
It would be amazing if they did though, but I doubt it.
Skype?
iChat?
Different Music App?
Streaming Music App?
Competiting Music Store App?
There's no way they'd allow these.
Possibly apart from Skype and a Streaming Music app why not? And the only real concern for those is when not on WiFi.
