i have a locked w580i, how do i get it unlocked?
If by "locked" you mean locked into a network, then the safest way to unlock it is to contact your network and ask them for the unlocking code.
If you mean that you've forgotten your phone lock code, then you need to return it to SE.
If you want to unlock by yourself then can try this link http://www.seunlock.com/ but as Drchris has already told that not very safe way way if you are not expert.
if it is locked to network then you can unlock it using codes. you can get the codes either from your service provider or from other online providers like Classicunlocking.com. if it is security locked try to reset it.

What do you mean by inverted? are you referring to the color or something else?
