I've got a 16GB G1 Touch and want to upgrade to a 32GB but now I find the 2Gs won't charge on my speakers or in my car (and, now I think of it, my Power Monkey). Is there any way round this? Can I get a new 1G?
If it won't work on the 2G but did on the 1G then the charger is more then likely Firewire-based, and as of the 2G touch no iPods support Firewire anymore. You'll have to track down a refurbished 1G on the Apple Online Store.
