Ok, so I was talking w my boy Phe-Nom and thought I would post this. It is nothing new, I TAKE NO CREDIT FOR THIS, I am just passing the info along that I fiound a long time ago. I looked around and didn't see this posted, also, if Phe-nom was asking me this I thought to myself it must not be on here. So here is the step by step process of what to tweak and what it does. Most of this will boost your signal strength and you priority to the tower itself! ENJOY~

You can tweak your Slot Cycle Index (SCI) to make your phone poll the tower more often. This makes your texts and phone calls come through quicker. This setting is a trade off between lag (most noticeable when receiving calls) and battery life. The default value on our phones is 2. Every step of 1 adds 1.28 seconds to the poll time, so at a value of 2 it is only polling every 5 seconds or so. Most people lower this to 1, so the phone polls every 2.5 seconds. This won't affect battery life much in areas of good coverage, but may impact it noticeably if you're in a poor reception area. Your Access Overload Class (ACCOLC) determines your phone's priority on the cell tower. The higher the number, the lower the priority. Do note that 0 and 1 are reserved for emergency service uses, so DO NOT use these. You can ACCOLC's of 2-9, default on Sprint should be the last digit of your phone number.
Now that I've laid down the basic groundwork of the two main mods, here's how to change them. Don't mess with settings in here unless you know exactly what you're doing, as phone performance and usability will be affected. To enter programming mode, open your phone screen and dial ##778# (may be ##778 on some devices, if that doesn't work, run EPST.exe from \Windows). Click edit, type in your MSL, and hit OK. Now choose View Info in the lower left corner, and hit NAM settings. On this page you can change your ACCOLC (remember, don't use 0 or 1). Now, switch to the Modem Settings page to change your SCI (default is 2, valid values are 0-7). Now accept the changes and soft reset, and you're updated!

I can confirm these are valid and do work and help if tweaked corrwectly. BE SURE TO NOT USE 0-1 IS RESERVED FOR EMERGENCY USE ONLY!!!!!!!
