Unlock W580i bought a IMEI but what is NCK

[swindlerz]

If your phone have a "JOGDIAL" (ex : SonyEricsson K700i) you must press "down arrow" instead of "left arrow" for step 2 & 3. We mean by "Down Arrow" to direct the Jogdial down !
Monodrive

maybe for some phones but not k700i because i have that phone and can confirm its left arrow not the down arrow same as k800i.
