One thing you will have to remember is to install the software for the particular phone (i.e. 8300, 8310, 8320, 8330) I mistakenly installed the 8320 on my 8300 and everything worked fine except my camera. Each time I tried to open it the software locked the phone up and the only way out was a battery pull. So be sure you only install the latest software that applies to your phone.

Thought I would share this as I learned my lesson the hard way!! (seems I do that often.)
