My 3G unit arrived on Friday. I immediately tried to sinc it to my home network. It recognized it and asked for the password, after which it kept trying to sinc, but was unsuccessful. I also have two Bluetooth headsets that I tried to sinc to it. It recognized one of them, but failed to sinc. Set up the 3G. It couldn't have been easier. Went to the local Apple Store and told them of my problems. They were able to sinc my tablet to their store's wi-fi network, and they also got the Bluetooth to work with one of those expensive Sennheiser headsets. I didn't want to spend nearly $300 on a headset, so I bought the Apple wired headset for around $30. Has anyone encountered the sincing issues?
