The 16GB white and blue verizon galaxy s3's are $149 at Amazon. I wish I could use it, but I don't have an upgrade. I'm getting the phone next through a rep moving an upgrade for a bad refurb phone, but I thought I'd share with everyone who might have an upgrade. I think AT&T's are the same price, but I just put links to Verizon.
