Number portability for all!

Today's the first day that cellphone number portability goes into effect for the entire country. Didn't this already happen back in November? Yeah, but only for the top 100 markets. Now the FCC is requiring portability for the rest of the country (about 25% or so of the population) that wasn't covered before. And just like last time, today is probably not a good day to try and switch your service.
