Much fuss has been made about the iPhone 4’s reception woes, but the evidence continues to mount that suggests the problem is purely the result of a bug in the current build of iOS 4. As proof, a YouTube user has posted a video of his iPhone 3G, held in a similar fashion as the iPhone 4s in the YouTube videos we showed you yesterday, losing signal strength as soon as it is clutched. As this did not happen with iOS 3.0, this suggests a software bug which affects the signal meter the user sees. Even more interesting is the fact that despite displaying a weak signal — and in some cases no signal at all — many users report that the iPhone 4 is still able to make calls as if nothing were wrong.
