Stupid question but really I don't know how to ask it so please bear with me.
I very ignorant about mobile phones. I need to learn about the networks and hardware. Not so much programming but hardware(typical architecture) and networking(protocols, infrastructure(cell towers and technology there), etc)
Anyways, I'm kind looking for a book that can get me uptdate on current mobile techonlogy. I guess something like an equivalent of an A+ type book but for phones.
Maybe someone here could recomend a reference or even online resource?
