1. Calendar widget. Shows events that are happening within 2 weeks correctly, however it fills the rest of the list with events from any time in the future. Example, I have 2 events within 2 weeks which are displayed correctly, I also have 4 events happening in 3 weeks (which aren't shown), but it is showing events that are happening in October 2010.
4. Not really a bug, but when new email is received, if you click on the notification to view the email, it is impossible to delete it. The delete button is greyed out. It appears that you have to load the full email client to get delete abilities.
5. I've also experienced the rapid battery drain problem. This was at a location where although I could connect to the open wireless account, it needed further authentication for me to browse the web. Maybe the applications were trying to update themselves without success, but it managed to drain the battery in 4 hours flat.
Other than these minor problems, this is the best phone I've ever owned. Coming from E90, HTC HD, HTC Touch Pro 2 to N900 was the best thing I've done. I hope that proper MSN messenger and facebook chat arrive soon, as this will become a communications hub for me. Cheers, Andy.
