AppleInsider highlights a new research report from Piper Jaffray analyst Gene Munster which found that the resale value for Apple's iPhone 4 has risen since April.
Specifically, Munster and his team found that the average resale value for the iPhone on eBay increased by 10.31% over the past few month. In contrast, the resale values for both the iPhone 4S and the iPhone 5 both dropped a bit on the popular auction site.
Clearly, there's still a significant number of people who want the iPhone 4, which is rather remarkable given that the device is more than three years old at this point. Indeed, Tim Cook has stated on more than one occasion that Apple has been surprised by the consistent interest in the iPhone 4.
As for the drop in resale value for the iPhone 4S and the iPhone 5, that can also be interpreted as a good sign. If the resale value on Apple's most recent smartphones are dropping, it stands to reason that supply is greater than demand. Consequently, it follows that many folks are looking to dump their current iPhones ahead of the impending launch of what will likely be the iPhone 5S sometime this September. While it's also possible that these same folks are interested in Android-based devices, iPhone consumers, once in the iOS ecosystem, tend to stay there.
