Update

Warning: It reflashes your phone and you lose all data and changes you have made.

I seemed to notice better call quality after doing the update. I was pleased and it only took me 10 minutes to get my settings back to normal.

If you have never done a flash install, the download comes with a .pdf of step-by-step pictures.

Does it lock the phone to ATT or does it just upgrade whats all ready there?

I've unlocked mine to use on a different carrier and don't want to do it again.

It would undo anything that you have done to the phone. So yes, it would lock it back.

While it does perform a hard reset to the phone (all data and applications erased), it does NOT re-enable a service provider SIM lock if you've previously unlocked.

Nice. Thanks for the info. I figured it totally reset everything.

I'm not aware of any ROM update (for a Windows Mobile device) that has re-enabled a service provider SIM lock, so I updated my device without hesitation.

I just saw that this update was available and plan on installing it over the weekend. Is there a set of release notes available, or am I just overlooking it?

Has anyone seen an improvement when using bluetooth headsets? Right now the Duo seems to really hate my H700 headset. Currently, I have to turn on Bluetooth and then power cycle the phone before I can use the H700 reliably. Even then, everyone complains that I'm extremely loud. I didn't have these problems when I had an MPx220.

Just an update... The ROM upgrade fixed almost all of my Bluetooth issues. Call quality is better and I don't have to power cycle all the time when toggling Bluetooth on and off. I like my phone much better now.
