Hi, I travel a lot by bike and public transit, so risk running out of juice on my Fascinate, with no outlet around to recharge it. What do you think would be the most convenient/least hassle to carry around: A spare 1500mah battery; or a pocket battery charger? What happens when you take the battery out of the phone and put a spare in; does it reset everything? You'd have to stop your phone call, at a minimum, right? If a battery-operated pocket charger is the answer, I'd want one that will take rechargeable NiMH AA or AAA batteries, because I own a nice battery charger for those. The idea of an *extended* battery does not appeal for some reason. It is expensive, and I like how slim the phone is without it. - Lisa T.
