A group based in Egypt, called themselves iPhoneIslam, succeeded in changing the iPad 3G into the phone! Through the jailbreak process, they demonstrate how iPad 3G can contact/call to/from the iPhone 3G and iPhone 4. Also, send and receive SMS messages to/from the iPhone 3G and iPhone 4. FaceTime also use the video call via phone number is also a success.
Do not worry, you will also be able to do so. They will provide PhoneItiPad, that’s the name of the firmware that, in Cydia app store. In fact they warrant prior to the WWDC, PhoneItiPad been available in Cydia. Jailbreak process requires no additional hardware other, only a jailbroken iPad 3G. That’s it.
When you have installed the firmware in question, it will appear the dialer screen. Unfortunately, the dialer screen is not something new but it is an iPhone version of the zoom 2x. No wonder if the quality of graphics that look a bit bad because it should be imposed on a screen resolution of large iPad. But actually not really a problem because the phone, SMS and video call can work very well. Please see the video below:
