I’m definitely not going to advise you to jailbreak your iPhone or iPod Touch, because I believe it’s easier for you to download unsecured packages (software) and be susceptible to being hacked that way.  Still, if you want to jailbreak your iPhone or iPod Touch to make it looks like iPad, then you can!  I’ve found a source that shows you how to turn your i-whatever into iPad, but it’s up to you to take the risk of making your iPhone or iPod Touch less secure!  For step by step of how jailbreaking your iPhone or iPod Touch, you can also check this source out (this guide is for Windows 7 and Vista users only).  You can also check out the video which shows you how to make your iPhone or iPod Touch looks like iPad after the jump!
