It definitely reminded me of a standard Nokia battery. I have a couple of Nokias laying around, I could play with that. My current solution is to carry my iPhone 4 and a Nokia E66 when I am abroad. I really like the Nokia phone, but there is a convenience in doing everything on one phone and the GMate takes less space/weight in my pockets. I'm divided, however, because my Nokia is 2100mhz 3g and I have Jokuspot on it which opens up foreign data options to me. While my ATT SIM covers my foreign data, I am also sensitive to the fact that ATT pays attention to users on this plan and don't want to abuse myself. When I was in Cambodia and Hong Kong, I could buy gigs of data for pennies. When a gig of data cost me $4 it seemed stupid to press my luck.
