While I'm waiting for the FedEx man to come to my office, I've installed iTunes on my work PC, and hope to do a quick activation followed by goofing around with my new baby for a couple of hours before I get home in the evening. My question is -- if I do this, and download some apps over the 3G network before I get home, will there be any problems when syncing with my Mac? Will the apps that I've downloaded be in danger of being wiped out? Do I need to set up this freshly-installed copy of iTunes with my iTunes store name and password before activation? I imagine that there wouldn't be a problem (since iPads are being activated in Apple stores), but if anyone knows for sure I'd appreciate any advice you could give.
