I've recently installed 5.0 on my Curve and now when I try to use my speed dial on the letter A it locks the phone.

I checked my speed dial numbers list and I also found the letter Q changes profile to vibrate only.

Anyone knows how to change this?

Thanks.

No. The "Q" and "A" keys became hardcoded. Some will say that you can go into the Speed Dial settings and change them, but once you reset the phone, the changes are lost.

Yes. I use the program shortcutme, so I am able to use A for different purposes once I hit my convenience key
