Apple has released the iOS 4.1 software development kit (SDK) to developers, leading to speculation as to whether a cure for the infamous iPhone 4 'Death Grip' problem may be on its way.
The company had insisted that the dropped calls experienced by users of the iPhone 4 were due to a problem with the algorithm used to display signal strength bars on the phone.
There is, however, dispute as to whether the reception issue will be fixed by the iOS 4.1 firmware update.
Many experts believe the problem is hardwarerelated, but Apple has maintained that no hardware issues have been found with the phone.
Technology magazine T3 reports that the update will add new features to the iPhone 4, iPhone 3GS and iPod Touch devices, including an improved Game Centre and a watermarking feature for jailbroken iPhones.
Currently the SDK has only been made available to developers, and Apple has tightened regulation to prevent the SDK being leaked online.
