You could update your firmware, but first you must check the version, try method in my post to show the hidden partition and see if the files BASE.RKW in folders SYSTEM and SYSTEM00 are updated after 13 october 2008, if yes, you have the more update firmware that you can find in internet.
If the files BASE.RKW in folders SYSTEM and SYSTEM00 are older then 13 october 2008, you can download the more update firmware here:
Download
But please, if you have a firmware newer than mine, extract it how I've described in my post and the upload it here:
