"unknown device" on powerdeck

[spiffyjiff]

sorry if this is redundant, but i DID use search function and didnt find anything...

i've accessed powerdeck from my touch diamond before (to get the pic mail update, etc) and all seemed fine. but today it said "unknown device" in top left of home page (and consequently no software updates/info). i'm not 100% sure, but i THINK this change occurred after i fiddled with the opera.config, user agent (hoping to default to full sites, as opposed to mobile sites).

question is how do i re-register my device or whatever.

please help someone!!!

thanks.
