Improve Latency and Speed

Hello,

This has come to my attention as a not so apparent but significant tweak avaliable to sprint users.

Basically, sprint has 6 areas, 1-7 except 6. Each area is served by two or four HA nodes and all your data goes through that node, regardless of where you are. If you're node is area 1 (California~) and you're in new york, your data bounces around from new york to LA before it hits sprint's backbone. Also, some areas are more congested than others. To fix this issue, you can manually change your HA node, or hope IOTA is treating you well.

Mogul/HTC Specific:
1) Get MSL code
2) Go to ##pst#
3) go to modem profile 1
4) set HA primary / secondary to something you like (see link below)
5) test pings to your favorite sites and speed test

to make sure its working, visit http://www.dslreports.com/mspeed?whoami=1&w=
it will say DNS: areaXX.spcsdns.net

I found Area 7 to be good to me for bandwidth and area 4 to be good for latency.

With no change in signal strength or tower or moving the phone or kicking people off the tower or changing the cost of data plans, I was able to go from 190-200ms ping to google and 650/250 to 1050/300 and 150ms to google.

Also, 255.255.255.255 is some kind of automatic selection ip.
