Be careful using Sony Ericsson update service

i used SEUS yesterday, it said no update available and my CID is still 52

depends on your phone and IMEI. let's say you have a W580 (which can be upgraded to CID53) and your IMEI is not on the list, then your CID won't be updated.

my sons k800i updated to 53 and locked, he contacted orange his provider said he wanted to use it overseas, paid 19.99 UK and got the unlock code, although they said it could take 3 wks (they needed imei) it took 4 days, and a full unlock code was received
