Dunno, I direct linked 2.0, and it told me there was 2.0.1 update available and downloaded it. Now if I can just get the darn thing to quit forcing me to restore from a backup, I'll be happy. (It's restoring for the 3rd time in a row now.)
Update: Ok, 3rd time was the charm. It was the longest backup of the 3, like 30 minutes (for what, I don't know -- I have about 10 apps on there, a couple dozen calendar entries and about 8 contacts total.) But it finally rebooted and did NOT ask me to restore from a previous backup.
So, installed 2.0 from a direct link, and updated to 2.0.1 with only minor technical problems. I don't have a problem with direct linking 2.0, because I bought the Touch after 2.0 was out, so the darn thing should have come with it anyway.
