I just went to go check out the GSIII at the T-Mobile store nearby, and I can confirm, that mess looks purple (the blue one that is). It was a beautiful phone otherwise, I just don't know if I was diggin that purpleness. I might be able to go with the white- I think the whole "White phones are for chicks, man" thing is done. Since the iPhone 4 was released in white I'd say about 35% of white iPhone users are male.
I might pull the plug on my pre-order all together and just wait for slew of Nexus devices coming out. I've got a year left on my contract, maybe I'll just ride it out and go with a Nexus + T-Mo prepaid after this. Definitely not going with a purple phone.
