I just checked and the new values are:
HTTP PD Proxy Port:0
HTTP PD Proxy Address:0.0.0.0
So it's the same as the fix that's been on the forums for a couple months, except Sprint is now "admitting" there was a problem and will fix it for you if you're not comfortable with going in through the MSL (which is admittedly easy and I had already done, but had to hard reset my phone to fix the Hotspot and it went back to the bad values when I did). I was just surprised to see the message come from Sprint themselves.
Thank you for verifying that. I appreciate it.
