Well , I called 611, and went through their revised prompts.
I got ahold of the CSR and they did an ESN change quickly, and without a hitch.
They did ask if the phone was a flashed phone, and I answered truthfully that it was (I needed to see if their response was now different).
There was none of the previous littany of "your phone won't be able to browse, or send/receive MMS" many of us have heard for so long.
They asked if was a "fully flashed" phone, and when I said yes they told me to just do a *228 after I hung up.
Honestly, that was the fastest ESN swap I ever did.
