Wallet PIN - inaccessible

[inocane]

Today after a week or so without using it I cannot access my wallet any more!
I didn't change PIN, I remember RIGHT PIN but it shows "Wrong PIN"
Maybe it has something with unlocking phone, switching sim card couple of times....?
As I learned ONLY way to change pin now is "factory settings"..... :angry:

So used the factory brick function......
After "while" restored most settings/stuff - Games resets (cut the rope.....) Few settings gone (calendar colours...) 3rd party programs data/settings gone.......
only because I want have a possibility to PAY for new apps......
