I have had my N900 from the UK launch, and have been over the moon with it. I have installed OVI applications and ones that have been put in the tried and tested respository on here - playing it safe.
However, all of the sudden it tells me my memory is full and cannot receive SMS messages, yet my settings tell me I have 27GB memory free and 1.65GB free in the system memory. When I try to delete SMS messgaes it says delete, but when I press delete it stays there and the SMS remains.
IT has come to the point that I tried rebooting my system by removing the battery, but now it boots up, gets to the desktop and the only way I can describe it, green luggage labels appear as widgets, it hangs, then reboots again, and again.....

Please help, and I am a complete novice when it comes to systems etc.

Thanks
