There are rumors that a fix to the death grip of the iPhone 4 with Monday’s iOS 4 update.
About two days ago I wrote about what Steve Jobs had to say about the poor signal the iPhone 4 gives or in some cases no signal at all, when the lower left hand side is touched. In that post I also wrote that Apple should fix the problem and not just blame us of holding it wrong. If this rumors turns out to be true then someone may have heard us at Apple since a fix could be coming. The solution could be coming with Monday’s update on the iPhone 4’s OS, the iOS 4.
The fix is expected to address a issue in iOS 4 related to radio frequency calibration of the baseband. 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.
Many iPhone 4 users have also corroborated the idea that the issue is related to iOS 4’s software control of the baseband, including the fact that the issue seems easily reproducible when connecting to a WWAN 3G network but does not appear when connecting to a Microcell 3G. There is one thing to keep in mind though that if the problem was a hardware related issues of the antenna design, it should only affect iPhone 4 units with that new design and should occur at all times, regardless of the tower type.
We know how these rumors can be, sometimes the turn out to be true and sometimes they are not. I guess we are just going to have to wait and see what happens.
