This is a semi-odd one. I bought a new Mac Pro last march and bought an iPhone 3G when they launched in the UK. I tried putting the iPhone 3G in my old third gen iPod's docking station connected to the Mac via USB and to my surprise it worked perfectly. It charged and synced the iPhone flawlessly each and every time I connected it even though a message appeared on the iPhone screen informing that the accessory was not made for for the iPhone.

Anyway, the Mac Pro broke down in December and Apple decided to give me a new replacement. I've updated the replacement Mac Pro (which is the exact same spec) so that it perfectly mirrors my old Mac Pro, but now the dock wont charge my iPhone anymore. It syncs but doesn't charge.

I've been trying to figure out why this is? Maybe because a newer version of iTunes was released over christmas that the new Mac Pro updated to which told the dock not to allow charge? Or maybe because the new Mac Pro just has different firmware that's blocking the old accessory from working?

Whatever it is, it kinda proves that the block is probably software based (as it worked perfectly on the slightly older replica machine) and that it's a way of forcing me to spend some of my cash on a new docking station (cos I hate just plugging it in to the cable).

Mac Pro 2 x 2.8 Quad Core, MacBook Pro 2.16 Dual Core & iPhone 3G, Mac OS X (10.5.4)

    Does the dock charge your iPod? Or can you charge your iPhone on another computer using that same dock?

    It's possible that something may have happened to the dock. Try the above suggestions to try and rule out where the issue is.

    It seems to work intermittently. I actually did charge successfully using the dock connected to the Mac Pro this evening, but other times it has refused to charge. It can be quite frustrating leaving it on the dock having watched it sync, thinking it's charging, only to come back two hours later to take it out with you but find it's got less than 10% battery power.

    Ah well. I think the easiest answer will be to buy a new dock.

    After a couple of days trying and testing it looks like the problem is something to do with the 4 port powered USB 2.0 hub that the iPhone 3G cable plugs into.

    There are no other devices connected to the hub except my Dell 2001fp monitor which also has 2 open USB 2.0 ports on it. The only port in use is the iPhone cable, plugged into my 3rd Gen iPod cradle that I previously used to charge and sync my iPhone 3G.

    Since being given a replacement Mac Pro by Apple, the iPhone 3G no longer charges at all when plugged into the USB 2.0 hub. It won't charge connected to the new iPhone 3G cable, or through the cradle, but it syncs perfectly. It charges perfectly when I plug it straight into the USB socket on the front of the Mac.

    Oddly, the charging battery icon does display when the iPhone 3G is connected through the USB 2.0 hub, but it just doesn't charge.

    I've just found that it even charges when plugged into the Dell monitor USB ports which are plugged into the USB 2.0 hub!?!

    To add more confusion, the battery level indicator on the iPhone 3G display seems to jump intermittently when connected and de-connected from the Mac Pro. When I removed it from charging whilst plugged into the front USB 2.0 port on the Mac Pro, the battery indicator showed 50% But when I then plugged it into the Dell monitor USB 2.0 port the indicator shot up in one jump to about 60%

    Stranger and stranger!
