I upgraded to this sw yesterday using PCSuite. I restored all my applications, contacts, messages, etc from the backup stored on the N900.
Since that time I am experiencing fishy operations of the message/call log. Somethimes the threads of Skype for different persons are mixed (at least, when I click to a thread, it opens another conversation, which I know doesn't belong to that person). Also sometimes I know, that I received an SMS, but when i go to the conversations, I can find nothing there or I can see something, but with no recipient's name or phone number.
And what is even worse: suddenly all my SMSs disappear. It happened with me twice today. i tried to delete the database file, I thought the structure might have been changed, but it did go better.

Does anyone else have the same experience or is something wrong for me only? One extra info: i am using the same Skype account from my PC also, so sometimes I reply from the PC, sometimes from N900. It had issues with PR1.2 also because of this, but far not this serious! My messages were there, simply it was diffucult to open it, if I replied last fro the PC to a thread.
