My contract came due and I took advantage of upgrading my phone from an iPhone 4S to an iPhone 5S. Do not really need (and kind of afraid I will break) a 6 - the 5S was $99 with a two year contract which is fine. I try really hard to stay in the technology trough immediately following the wave of teh "next new thing"
While i was at it I changed my plan; I had a grandfather'd unlimited data plan, but I've only been using 2GB / month, and that's in spite of my 4S wifi being broken since I upgrades to IOS 6. So....I'm guessing I'm safe with a 3GB plan. In any case, unlimited talk, text, etc. for $10 less a month.
