So i'm here in my house, were on my old razr i got pretty good service. But now with my iphone, my service keeps fluxuating, like going from 3 bars to 5 bars and from full bars to none at all! and im sitting completely still! Is this a phone problem? Because if it is, i want it fixed! i payed 600 freaking dollars for this thing and i want it to work ya know? thanks for any help.
