about my phone

I bought my phone a couple years ago its a w810i. i bought it from this Chinese place and there isn't any logos other than Walkman and the activity menu. does that mean my phone was unbranded from the box or do i still have to unbrand it? i can play full songs as ring tones and its unlocked if that's of any help.

a branded phone means you service provider logos appear on your phone. if the only logos you can seee is SE and walkman than it means your phone is 99.99999999% chnace that it is unbranded. may i add that most chines phone are unbranded.
