I am also experiencing problems with the SMS counter after sending messages - not counting sent messages.

I am using the 2.01 Registered Version (if that makes a difference).

Another problem I am having is when I go into the settings for any reason, my minutes seem to roll back to where they were since the last time I was in the settings - ie:

I had 87 minutes logged after being the the settings.

A few days later I had around 128 minutes and I went into the settings to show someone the features of the phone.

When I exited the settings, I seen that it rolled back to 87 minutes.

I am using the HTC P3300 w/ WM5.
