Did the new firmware help anyone with the notorious WLAN-problems? Knowing they did some bug fixing in this area would be the only reason to go through the backup/update/restore-process, even though there are known new bugs; right now, not beeing able to connect to my WLAN-router, the 770 is back in its box waiting for better times. (A WLAN-device that doesnt do WLAN is not too useful, after all...)
