I've got 5 new apps stuck on waiting. I updated an old app in the meantime - no prob. The prob occurred after I updated to the new....? I've pressed an icon, they all shake, but no 'x' comes up on the waiting icons. I've deleted ALL my podcasts. I've reset the machine. Nothing works Any advice. P.S. I ONLY have an iPad, no other Apple products, so can't sync to anything.
