I upgraded to the new version 20 firmware the other day...
A few things which are not better than v12 (or is it just me)??
1) you cannot see more than 2 entries on Active standy for the calendar.
2) when you turn the battery tones on silent - you still get an alert when charging or the battery is full
3) when connected to a bluetooth handsfree car kit - in v12 you could set a profile with no warning tones/
i.e. no low battery alert. on v20 I have done then same but it does not work - prompting my car kit to turn off the radio every few minutes to connect to the phone!
I have flashed it 3 times now, so it does not look like the handset?
Any ideas - or anybody having the same... might as well get a roll back to v12 if that would ever be possible without frying the handset....
