Heres something I discovered last night, appologies if this has been discussed before. My wife are on a AT&T family plan w/ 2 different iTunes acccounts. I just updated my iPhone to 2.0.2 from 1.1.4 two nights ago. My wife updated to 2.0 1st day it came out. She bought the Apple Hold'Em game on day 1. Last night I was looking for apps (on my iTunes acct) to dl and didnt want to re-buy the Hold'em app. I downloaded some free ones and couldnt sync'd it. I got an error that said that my computer wasnt authorized to use those apps. Thats it, it didnt say how to resolve it. I then went to my wife's computer and plugged in my phone w/ her iTunes acct. It reconized my phone and I sync'd the Hold'Em game to mine. I then went back to my computer and my iTunes acct and re-sync'd. It asked me if I want to copy over the new app from the phone to the computer so I did. I then got an error saying that the App (hold'em) wasnt authorized to play on my computer and said to go to store>authorize to authorize it. I did that and it asked for my itunes user name and password. I figured since it was my wife's app I should put in her info and said something like 1 or 5 authenticated. Bottom line - We both have Hold'em on our phones and 2 different itunes accts and paid 1x for it.
