Apple investigating issues with iOS 4 upgrade on iPhone 3G

As more and more two-year veterans of Apple's phones have taken the plunge and upgraded to the latest firmware, slowdown and battery drain issues have become a common complaint, which is even more irksome when you think of just how little the update really adds to the UI. The Wall Street Journal reports speaking to an Apple spokesperson who said the company is looking into the matter. That doesn't necessarily mean a fix is coming anytime soon, but hey, at least you can hold the darn thing however you want.
