unlocked iphone
not sure if people are still looking for a solution or not, but this is what works for me...
i've found that unlocking a first gen iphone i acquired here recently allowed me to sync after I removed the sim. once iTunes was happy with the sync, i put the sim back in and i had a fully sync'ed calendar, contacts, mail and so on. removing the sim every time is somewhat annoying, but without having it be legit and upgrading to the iPhone 2.0 software that iTunes is trying to shove down my throat, it's the only solution i've found.
