I have a nokia 5800 XM from t-mobile UK. Its currently at firmware V.10
I need to unlock it to use it on any network.
Will the following steps be good enough:
1. Change product code to generic code of APAC region using NSU
2. Update the firmware using NSU to V.20
Will the above steps debrand AND unlock the phone?
i guess it only lets you upgrade fw to the latest one

NO m8, de-branding and unlocking are totally different. (By the way de-branding totally invalidates your warranty!)
You need to buy the unlocking code directly from T-Mobile, or take your handset to a back-street phone shop and pay them to unlock it for you.
The above mentioned site do not provide unlocking information about 5800 - it is not in the list at the current date.
First you have to purchase the unlock code from http://www.mobileunlocksolutions.com/unlock-your-phone/rs1wp2/
