Hello all. I am stoked for the release of the iPhone 3g, but also disappointed at the same time. This is mainly due to the removal of the brushed metal back, as I thought that made an iPhone look very unique and distinguishable. Basically, I am trying to decide whether or not I should find a v1 iPhone with the metal back, or at least wait and try out the iPhone 3g. I mean, even though the case is "plastic", it still has the potential to feel high-quality and whatnot. I guess I won't know until I hold it for myself. So really what I am asking, what are my incentives for going with an iPhone 3g over a v1 iPhone or vice-versa? Is it simply the addition of GPS and 3g? Or are there more things to consider that I am unaware of? This will be my first iPhone, so it's not like I'm trying to decide whether or not to upgrade -- just which one to get.
