Apple recently announced that they have sold more than 1.7 Million iPhone 4 units and reported that it was “the most successful product launch in Apple’s history”. iPhone 4 offers more than 100 new features and the improved camera and FaceTime are undoubtedly some of the best features.
Before iPhone 4 was officially launched we started hearing about reports that users who received their iPhone 4’s were experiencing reception issues when the phone was held in a particular position covering the lower part of the stainless steel band. When a user emailed Steve Jobs about this issue he replied saying “Just avoid holding it in that way.” and Apple also released a press release where they accepted this issue and generalized it by saying:
This is a fact of life for every wireless phone. If you ever experience this on your iPhone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band,
Recently another iPhone 4 customer wrote an email to Apple CEO pointing out the signal issues and this time Jobs reportedly said “There is no reception issue. Stay tuned.”
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.
Even though the existing reception issue doesn’t seem to slow down iPhone 4 sales however, it would be interesting to see if a software update could solve this problem.
