please help an old timer with 2 easy questions

[ghersh]

1. When I'm not in the car paired w/ my blutooth car kit, should I turn the bluetooth off on the phone? Whether on or off, my battery lasts long enough that I don't ever have to charge it during the day.

2. I recently upgraded from orig. sprint Rom 2.08 to the current version. I love the GPS. On the old version, I ran HTC X-Button 1.5. This new version has 2.0 built in. I know in 1.5 it would show me Comm Mgr running, but w/ 2.0, I have to do extra clicks to get to the task manager to see that it is running. Any way to "downgrade" without having to cook a rom? Maybe turn off via a reg hack and then install 1.5 and put in startup?

Thanks in advance,
Greg
