There is another issue that I just identified on my 8700. When you hit A to got to address book and then type some letters to jump to the desired contact. Say you type 'Joh' and you got to John. Now you delete the letters using Del key and once you delete all three letters 'Joh' and you still keep pressing delete key. it will prompt you to delete that contact that is selected on the list. And this way I hace already deleted 3 of my contacts.
This is a serious bug and it does not happen on my 7290. Unless I am missing something in my 8700. I checked the settings on 8700 and 7290 and they are same.
Can someone confirm this.
