for checking no updates in your region or just problem with you phone use:
1. open x-terminal
2. sudo gainroot (You need rootsh package installed)
3. apt-get update
4. apt-get upgrade
On question upgrade answer no.
Before answering look on list available packages for upgrade....

if you will see applications from list: http://talk.maemo.org/showpost.php?p...4&postcount=16
It is mean problem with your phone and you install packages which prevent you from upgrade. In this case place on the forum question with outcome from "apt-get dist-upgrade" (but answer NO on question install?)...
