So I've had a restriction lock on my ipad so my kids, who play with it more than me, don't go deleting everything. But now I want to do some clearing out of apps that we don't want or need and I can't seem to be able to change my restrictions. It comes up with a 4 digit pass code panel, but I don't recall ever putting a 4 digit password on here. So I've tried a few codes that I usually use, but no success. Every time I try a new code the counter keeps ticking up. I'm up to try 5. I'm worried if I keep going the whole ipad will shut down on me. So my questions are: is there a limit of password entries? And, if I can't remember the code is there another way to get around this problem?
