So much easier to do than it was on the instinct! Get your MSL and do some stuff from this thread: Samsung Instinct Forum - Login
Make sure to read the instructions carefully, just as if you were using Linux code, and I guess instead of Updating Data Profile (which you had to do with the instinct), just reset your phone to have the changes take hold.
Give your thoughts on what you notice. On my instinct the changes were like night and day. Sprint Tv was way faster, and because you connect to a closer Home Agent, the EVDO is faster. Obviously Pretards are spoiled with Wifi option, but obviously when you aren't in a hotspot, every boost can help.
Again make sure to UNDERSTAND (not just read) the disclaimers. If you change your Home agent, realize that if you travel to another part of the country, your signal will still go back to the home agent locale first and that will cause a delay or no signal.
***Also very important***
Write down the initial values for everything you change. There is a reset defaults in the ##DATA# menu, however I'm not sure if that will basically wipe the whole cell clean, and you may just want to revert those couple settings....Enjoy!
