Well, now I feel stupid.... Thanks for the pointer, for some reason I haven't seen that particular wiki.
edit: Realized that it is the wiki I knew about, but just missed it somehow. Thanks!
Any estimate on when these would be available? I'm itching to get a nice battery pack for this to go mobile, but I just haven't found one I feel good about yet.
Is there a list somewhere of known working ones? I'm particularly interested in ones used by providers with either monthly or pay as you go plans (no contracts, in other words).
