I saw a thread a couple days ago (but forgot to save it and, given my mem probs, I should know better) that showed a small device that was a USB to 510 connector that was being used to connect to a dual output External Battery Charger... Connection would be charger to connector to atty... Anyone know what I'm referring to? Any help would be appreciated 'cuz the mod looked really cool and simple... Sure wished I'd saved the link...
