Has anyone experienced the phone not picking up incoming calls when the screen is turned off (wireless mode on)? I became aware of the problem when multiple people started telling me they had trouble calling - it sounds to them that the phone is ringing and then the call goes to voicemail.

After a visit to the Cingular store and a call to customer service, I realized that this happens when I turn off the screen.

Same problem reported at http://pdaphonehome.com/forums/showthread/t-36415.html , but no real solution.

Shouldn't the phone wake up to answer the call?
