Unresponsive iPhone 2G and 3GS
So I recently bought some phones and these were included. Here's the issues:
iPhone 2G (first gens) - one does absolutely nothing. I've tried 6 different 30 pins and a lot of electrical outlets. The other one boots to the Apple logo then turns off - I suspect it's a dead battery but I'm not sure.
iPhone 3GS - does nothing when plugged into power. One time it did boot to the Apple log but then it got stuck.
Anyone have advice/diagnoses?
