ST and AT&T got into a pissing contest before I could pull the trigger and port my number. So now, it is either T-Mobile or Verizon with them.
AT&T has started their own prepaid service,
Aio Wireless. Pretty close to what ST was offering. I may well go that way.
And I got a Nexus 5 yesterday. It is one of the few phones that I knew I would keep within 15 minutes of basic configuration. Just a touch (1/32") longer than my old Gnex. Great screen, really fast and feels great in the hand despite being an all plastic phone.
