Hi guys, need a little help.

I changed the background picture in winterboard. I chosed the "user wallpaper".

After the change my home screen is totally locked, when i press the back button it goes to the "search" page, but when i press the screen nothing happens.

When the locked screen comes up the touch works, I can unlock it by sliding it, but then its back to not working.

Even if someone calls me I can answer normally and the screen works.

I've tried to soft reset it by pressing the home and standby button för 15 seconds, the iphone restarts but the problem is stil there.

Is there a solution for this?

Thx
