When Apple, Inc. (NASDAQ: AAPL) released the iPhone 3G back in July, little did it know (most likely) that the device would have issues worldwide connecting to 3G networks, causing consumer frustration on a level we've rarely seen with any Apple product. Well, some consumers have apparently given up and they're moving back to the older, slower, original iPhone, which is causing a cottage industry to spring up around the older device.

NextWorth.com is charging $200 to $300 for a used iPhone (the non-3G kind), which is more than the price of the newer, sleeker and faster iPhone 3G. Why? There's demand -- and lots of it. Some customers don't want to be shackled to AT&T, Inc. (NYSE: T), the exclusive carrier for the iPhone and iPhone 3G in the U.S., as the original iPhone can be unlocked very easily using software tools found all over the internet. Once unlocked, the original iPhone can be used at any WiFi hotspot. There are no 3G connectivity issues either.

Does Apple have a problem now that the older, discontinued iPhone is still in hot demand? No. People using iPhones, new or old, reinforces the brand among other things, and Apple still made the original sale after all. If there is any loser here, it's AT&T. The largest wireless carrier in the U.S. still has the smallest nationwide 3G wireless network compared to its competitors. Launching a product with the magnitude of the iPhone 3G was just asking for problems given AT&T's network, and some informed customers don't want AT&T at all.
