My nephew had a new Touch at X-mas. He can't get any Apps to open. Please have suggested the restore from the iTunes site but no luck with that. I have a 1st gen Touch and have only had a similar problem with the odd app, resolved either by powering off and on the Touch and with others uninstall/re-install. To be fair though I doubt I have had this problem a half dozen times.

Any suggestions would be gratefully received.
