It didn't work. I tried to sync the purchased apps from my old 3gs to the 4 and it went through the process, syncing, took about 10 minutes, but when it finished there were no new apps on my i4.

?
Am retrying. Windows sent an error report "serious error."
 
Make sure you activate the iTunes account again (deactivate and then activate).

sorry, dumb q - you mean turn it on and off? I had to, it all shut down and restarted the computer... this time I am only trying to move over a few apps.
thx.

update: this time it went through. I moved over just a few apps and for some reason the old windows computer was happier with that.
