I have read the mindset for sometime now that it should be the end user, who simply avoids the problems with the iPhone 4 reception, buy simply spending money on another case. You know, because that $30 case for the previous iPhone is now junk.
I was pleasantly surprised however, to discover this article in which Consumer Reports indicates they simply cannot recommend purchasing the iPhone 4 due to Apple being unwilling or unable, to address the signal issue.
I for one, go back to the old ideal of not being an early adopter. As the iPhone has demonstrated, getting the latest and greatest early on, is not always a good thing.
