The iPhoneIslam, the people behind the Cydia tweak that have successfully enabled FaceTime on iPhone 3G, are back. Their upcoming Cydia tweak is said to enable cellular calling and texting on jailbroken iPad 3Gs. The privilege of turning your tablet into o huge phone will set you back twenty bucks. We’re guessing this nifty little program should tie nicely with Apple’s new iMessage feature in iOS 5, enabling both SMS and free iMessaging on iPads. The app is called PhoneIt-iPad and should hit the Cydia Store shortly.
