Use the "hidden menu" to set it ... in Gingerbread (on the Bionic) ...
Type in ##program and hit the connect key
When the display comes up type in 000000 and hit the Verify key
When the menu comes up select 06 Test Mode
When the Test section comes up hit the Next button at the bottom of the screen twice
Select the Service option at the top of the screen (it currently says EVRC)
Choose the EVRC-B option
Select Home button
You now have EVRC-B set until the next time you power off/power on. (Apparently earlier versions of Android allowed you to set it once and it was retained. Gingerbread resets it to the EVRC.)
I have not changed any other options on any of these "hidden menu" screens and do not know what impact changing any of them would have.
This single option seems to be "a keeper". I don't know what this option does to anyone's phone.
All I can tell you is that it is how I am currently running.
Just an FYI...
I tried this and it worked good, except that it broke my universal inbox notification widget. I got email but the widget no longer worked. I reverted and it's now working again.
