do you have vallid developer account ?
Beta 2 works fine on an unlocked 1G. Upgrade using the same procedure as for beta 1 (downgrade to 2.02, quickpwn RC3, upgrade to 3.0 beta 2, restore from backup).
Youtube is still not working though.
Not until there's an official release.
FYI : Since I went to beta 2, I've been unable to retain my lock. It just won't do the upgrade onto an unlocked phone and I have to restore instead which looses the unlock.
Correction to my previous post:
I had confused and messed up my upgrade path to 3.0 beta by putting in my legit sim, and so was getting "A different SIM detected" error. I corrected this and now have beta3 unlocked. :-)
If you have a working unlocked 2.2.1 1G phone then just simple shift(or option)-upgrade to 3.0 should still work for you too.
For those wondering, I just upgraded my beta 2 to beta 3 directly without having to downgrade first. My activation worked just fine, even though initially it showed 'No Service', soon as I jailbroke it using the new Quickpwn, everything works.
