I set as lockscreen a personal picture.
New born baby about 2 min after he is born.
I now have lost any other copy of this picture, but it still on my lockscreen when my iphone is disconnected (cable).

I tryed WINSCP, TouchCopy and many other i can't find it.
Any help will Be really apreciated!

By the way, i can't connect it to Itunes because i change sim card and the phone isnt unlocked yet Itunes tell me than i need to put the original sim. i will put gevey ultra in it, but i don't want to try anything that maybe could make me lost this picture.
My iphone is jaillbreaked.

Thank you in advance
