If you type it wrong 10 times, it locks for a minute (or delete all the content, if you have set it to do that in settings). If you type it wrong once more, it will be locked for 5 minutes. Once more, 15 minutes, and so on. If you forgot it, connect your iPad to a computer with iTunes with the cable, and reset the device.
Find the person who put in the code and ask them for it. No need to erase anything.
Yes, you can put a passcode on the ipad 2. Both the numerical one (one with numbers) and the keyboard one (where you type in a message). The keyboard one does look pretty sweet as it looks black, glassy, and shiny... you will still have to slide to unlock it and then a keypad/keyboard will pop up in the middle of your screen. To put it on the message type, you go to set the passcode then turn "simple passcode" OFF. Hope this helped.
why/how do you think you put it on wrong?
A passcode lock cannot be broken without resetting the iPad back to factory status and erasing all the data and apps. Forgotten Apple ID passwords can be emailed to you from the iCloud website.
No.
It does not beat
slide an put you passcode in
You can't put just anything on an iPad. It has to be made for the iPad. You can't just drag programs on the desktop to the iPad.
When you unlock a passcode that has been forgotten on your iPod Touch, all of your songs will unfortanetly be deleted, and you will have to put all of them back on. But if you are CHANGING your passcode, off of the settings button on your iPod Touch, nothing will happen to your current memory.
Depends on what kind of "wrong" fuel you're referring to...
Nothing Nothing
Put your iPad on the router.
