‘Death Grip’ to be solved in Monday’s update to the iPhone 4.

If rumors are to believed, Apple will be releasing an iOS update tomorrow (Monday), which will take care of the antenna signal issue, derided by bloggers as the ‘Death Grip’, that affects all iPhone 4 builds.

The update was referenced in a series of forum posts on Apple’s tech support forums (that have since been removed), implying that the signal reception issue is more of a software glitch than a hardware fault.

Apple Insider explains:
“Readers report that Apple’s tech support forums originally confirmed that a iOS 4.0.1 software fix addressing the issue would ship early next week (as early as Monday), before the comments were subsequently taken down along with all the other related discussion about the matter.

The fix is expected to address a issue in iOS 4 related to radio frequency calibration of the baseband. Readers who saw the original forum discussions say that the issue is believed to occur when switching frequencies; because the lag is allegedly not calibrated correctly, it results in the device reporting “no service” rather than switching to the frequency with the best signal to noise ratio.

iOS 4 introduced some enhancements to how the baseband selects which frequencies to use, so it makes sense that the error may have crept into those changes. Additionally, this explains why iOS 4 has also caused similar problems for iPhone 3GS users.”

The success of the update relies on if the problem is indeed related to a software bug. If it is hardware-based, Apple will have serious hell to pay.
