Having problems with my old Iphone I can't open it. When the screen pops up to punch in the code the 4,5 and 6 don't respond, the other numbers are fine. Haven't had this before, any suggestions?
Reset it by holding the home and power buttons at the same time.
Do you have too many programs 'open'? You can find out by clicking the round button on bottom twice [fast]. All the open programs will appear at bottom of the phone. Hold/press on one of them until they all shake and a little red 'x' appears on each program. Click to close them all, and start over.
Could help.
I don't know if you will be able to do this or not; try to connect it to iTunes and see if that way it will let you type your passcode.
