Couldn't wait, I got an AmpKitLink. Not as high fidelity I know, but a) it allows me to charge and play b) it's available now.
AmpKit is amazing, I got the Summer '11 pack and the Fargen, Sonic Edge models - and the Bogner model - are outstanding. The fuzz tones out of the J & J overdrive are really natural. The MobileIn should woek with it too.
