I used to have a Razr phone and a Sidekick phone sync their contacts with address book using iSync in Tiger. I then upgraded to Leopard and it stopped working. iSync says that both the phones are not supported devices. I was using the Razr and upgraded to an iPhone and my friend was using the Sidekick and also upgraded to an iPhone. Luckily all my contacts were saved from a recent sync. His were not. I need to sync his Sidekick so the contacts on his iPhone will be updated. AT&T says we have to do it online, but it won't work. Why did iSync work in Tiger with both phones, but with neither in Leopard! It is really frustrating! He has like 100 contacts that would be a pain to transfer by hand. Does anyone know how to fix this?
