I connected my iPhone (8GB, 4.67GB free) into my MacBook Air around 2pm this afternoon. It started the sync, and began doing a backup. Around 4:15, with the progress bar showing 2/3 complete, a message popped up saying the iPhone had been disconnected. (It hadn't, it was still connected and had not been touched.) I disconnected the iPhone, and reconnected it. The sync and backup process began again. It is now 7:25pm, and the backup show about 95% complete. Incredible! What the heck is it doing during all that time??!! I can't wait to get the 2.1 software tomorrow. I hope a "backup" works somewhat like a backup on any other device -- where backing up 4GB of data can somehow be done in a couple of minutes. As a software developer, I'm sorta curious to see what sort of bug has been causing the backups to take so long with the 2.0/2.01 software.
