The iPhone 3G has a few drawbacks when comparing it to the original iPhone – the biggest of which (for me anyway) is one that I just discovered tonight.
You can’t charge the device on an iPod Audio system. I have tried every one that I have in my house, including mStation, and others – and when you connect them, you get a message that says “charging is not supported with this accessory”.
This i only with the iPhone 3G, however. Original iPhones with the iPhone 2.0 software update still work just fine.
So what’s going on here? What is it inside the new iPhone that makes this an impossible thing to do? Any ideas?
UPDATE: As you can see in the comments the reason for this has been explained. Apple has abandoned Firewire as a method of charging iPods and iPhones starting with the iPhone 3G, and as a result any devices that used the Firewire method of charging will no longer work with the iPhone 3G.
So far I can confirm that the iPhone 3G will not charge on some mStation and XtremeMac devices – although it will work on the XtremeMac Luna. I will try to compile a list of compatible players in the near future.
It should also be noted that certain car chargers that work for the iPod will not work for the iPhone 3G either for the exact same reasons as the players. So be careful and do you research before you purchase a charger for your iPhone.
