Only time will tell

While mostly speculation, rumors mentioning the latest iPhone are floating around everywhere in cyberspace.  Manufacturing companies have reported orders being placed, patent companies have claimed they have the latest blueprints but who knows what true.  The point is no one really knows what goodies the newest iPhone will come with but even the pictures get me excited.  If Apple continues its tradition, there should be a new phone out sometime this summer but honestly the rest is up in the air.  Here are some prototypes (draw by non-Apple designers) and even though it's all speculation, it's still fun to see what the possibilities are.

I'm thinking I like the one at the bottom the best; something about the rounded edges and asymmetrical shape gets me.
