iPhone 3G accessory incompatibility index

As previously reported, many accessories that were compatible with the first-generation are not compatible with the iPhone 3G, either failing to charge the device or losing functionality completely.

We've compiled a list of incompatible devices based on user reports. If you have any to add, please let us know.

Will not charge the iPhone 3G: The explanation for this issue is as follows: most accessories on the market charge iPods/iPhones through either USB or a 12V connection that works through the FireWire portion of the pin connector. The latter method is cheaper, and hence more common. Apple has removed 12V (FireWire) charging from the iPhone 3G; this means that these devices are no longer able to deliver a charge. As such, some accessories will still perform their intended function, but fail to charge the iPhone.
