For those of you with I Phone charging issues... a friend of mine at work just got an IPhone and our USB charger wouldn't work with it. Turns out the IPhone looks for a signal on the data line rather than just using the +5V and GND. Turns out its just looking for 2.5V so a simple voltage divider (eg two resistors) will give you the 2.5V that you need. Since your source is 5V and its looking for 2.5V something like two 1K resistors should do the trick. My buddy did that and just soldered the two resistors and placed them in the 12V USB adapter.
