GumballTech found that if you enter your iPad passcode lock incorrectly a few times, the iPad brings up an Emergency Call Screen.
The above was easily achieved by enabled a passcode lock, and then entering it incorrectly about 5 times. You can then slide for a emergency call.
The Emergency Call Screen is formatted for the iPad with wider buttons and a centered keypad. Its unclear if this capability is required by the FCC; however, if the iPad can make emergency calls it will likely be hacked to make regular phone calls as well.
What's up with the little bird that follows as you scroll the screen? I'm not going to click on it because I assume the idea is to see how many people are SO intrigued/curious/annoyed that they do that.
