Has anybody out there been able to get the screen saver feature to work on a 9640? I've got an IPO 500 V2 running 6.0.8. Your supposed to be able to make changes to the 46xxsettings.txt file and force the phone to look at a different jpeg. I can't get the phone to recognize the screen saver timer or the new jpeg. Called tech support and they didn't even have a 9640 to work with yet, let alone have an answer. Tried everything I can think of but no success. Any ideas? Any help greatly appreciated!
