Hi guys.
DON'T do like me who tried the pattern to lock/unlock your edge! IT doesn't work and it WILL LEAVE YOUR EDGE LOCKED.
(bad things about NOT HAVING A REAL MARKET!!!)

Also some days ago I got a virus from what it was supposed to be an update for memory booster (the apk, instead, was a program to - no matter which action I did - open a email composer - supposedly to email the guy and pay to have it unlocked).

Fortunately, I solved both problems in the same way: restarting the edge and killing the program with the Advanced Task Killer before it even starts. Anyways, just a tip.

take care
