Ive got a generic iphone vs android question. I know with my iphone, after i switch, i wont be able to just use my iphone as an ipod touch. As soon as i reset my iphone back to factory settings, i have to connect it to itunes and sign up for service to unlock it. My question, is android like that? If i dont have a sim card in, or a service agreement as with cdma, can i still just turn the phone on and use it as a pda or pmp without cell service? Or does it tool around at a "looking for service" screen?
