I have been tethering my older MBP with an AT&T Tilt for the last year with great success and fast performance. Yesterday I went through the routine of pairing my Tilt to my new MBP (late 2008) and everything work up until I try and use the connection. Performance is extremely slow 2-3k and has long pauses. One thing pairing with the old MBP is very quick, the computer queries and gets the device details i just a few seconds. When I pair the new MBP after entering the pairing code the phone stalls for a good minute before it says its finished. Any ideas?
