I have noticed periodic delays of 1 or 2 seconds while I am typing texts or navigating menus which is a bit of a pain.
Finally, when you choose ringtones, there is one called "startup" which seems to be blank. Is this the same for everyone?
It wasn't until I found a newsgroup posting that I knew to activate the speakerphone by holding the green phone key! It is shown as a menu option in the Orange manual instead.
I also noticed that in the help menu for shortcuts, it says you can add voicetags to any contacts or a speeddial. I seem to only have the option for a speed dial, not a voicetag. Is there something I missed?
