This is irritating I have been searching for this problem and still need help when i hit the call button my phone starts dialing then goes to end call. I then hit dial again and it goes through most of the time. What is the fix for this. I have seen others talk about it but not exactly what fixes it.

Are you in a 1X data area? I had your issue and the only solution I could find was to disable push email and set to sync on any of the various intervals. My carrier, Alltel, was clueless about this. I found the solution here.

1X has another issue in that it doesnt end the data call after a sync and, unless you manually end it by holding the red call end button, then all incoming calls go to voice mail. Anybody know better about this?

I have gotten accustomed to manually syncing. Battery life is much better.

Cheers.
