Ring Lag Fix (SCI Method)
Hello. I posted this long ago on the Hero forums and it was pretty widely used with much success. Same method applies to EVO (I have already done it).
1) Call sprint CS and get your 6 digit MSL
-Root users can download MSL Reader from the market for free and get this MSL code without calling Sprint.
2) On your keypad dial ##DATA# (##3282#)
3) Select "Edit Mode"
4) Type your MSL as the password and hit "OK"
5) Select Advanced
6) Change your "Slot Cycle Index" to the value of 1 (explination below)
7) Press the Menu button
8) Select "Commit Modifications"
9) wait for your phone to reboot
Slot Cycle Index (SCI) - 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. If you lower this to 1, 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.

FYI, you can get your MSL without calling Sprint. Download aLogcat from the market. Fire it up, press home, fire up phone, type in ##data#, hold down home and switch back to aLogcat and pause it. You'll see text in green if you scroll up a bit with your MSL. Its a 6 digit number.

For some reason, It wont show up in the log for me.
Has that log method been tested with the evo?
Cause I clear the log, go to home, open dialer, enter the code, and switch back to alogcat, pause.
Now i see the log that shows my key strokes for the code, and there is not one string of 6 digit numbers anywhere after it. There are a few codes, alphanumeric, and a few that have 7-9 numbers, mostly 0s

I asked the guy at radio shack for my MSL code before I left with my EVO. He told me that EVO doesn't use MSL and instead there is a one time unlock code and it was printed on my receipt. The receipt shows a "OKTSL" code that is 6 digits. Is this true? Is there not a MSL anymore and it always needs an ever changing one time unlock code? I have not tried it yet. Anyone else have OKTSL code on their receipt?
2) It's OTKSL (one time keypad subsidy lock)
3) Try using the "OTKSL" on your receipt to follow the instructions. Worst case scenario it wrong and wont let you in. Will take you 10 seconds to find out.
4) The MSL is a consistent number. Flash, root, do whatever you want, it stays the same.
5) You will need this same MSL 6 digit number each and every time you enter the programming menu
Hope this helps!

That Otksl will only allow you to change the MDN (Mobile Directory Number, also your phone#) And MSID (not sure what that stands for off the top of my head) its for activating the phone on the network and nothing else so don't mess around with the numbers in there if you get into the menu. Probably easily fixed if you do, just thought i'd add my two cents. I work for Radioshack... Some people confuse the little bit that they know as superior knowledge then the customer possesses(My apologies for that). Thanks for this fix... does this impact sending of texts or just receiving texts on the queue in the towers?
Re: Ring Lag Fix (SCI Method)
Thanks for weighing in on the RS confusion. I know the rep didn't have bad intentions but at that same time, I don't like it when an un-informed person dishes out bad advice. I'd rather them say "i don't know", than spew inaccuracies. You seem to be a rare one and are actually educating yourself.

(quick note: keep reading because i completely disagree with him)
Let me explain it like this, lets say the fiber network that your home internet is connected to has 50,000 people and all are streaming movies at the same time. This would result in poor performance. Now imagine if 49,999 of those people stopped streaming movies .... as a result you (the person still streaming a movie) would receive better network performance.
I don't think he's implying that a single person doing this is going to increase your personal situation, what I believe he's implying if everyone did this it would provide an overall increase.
Here's why i disagree:
He's implying that voice calls and texts come through the EVDO network. EVDO actually stands for evolution-DATA-ONLY (emphasis is mine). Voice calls and texts are routed through 1XRTT, not EVDO. So polling the tower less often for calls and texts will not at all impact EVDO. What it will do though is save you some battery BUT also make your phone delay when ringing and receiving texts.
In terms of me providing proof, just do some research. I've added some links above but you can find links all over the internet confirming anything I've said . This is not a new method by all means. Us phone guys have been lowering the SCI for a loooooooooong time.
Hope this helps!

Re: Ring Lag Fix (SCI Method)
You should keep in mind this programming menu you are accessing is specific to Sprint. Because the ROM you are flashing is based off froyo, which is based off an AT&T/T-Mobile phone, this programming menu will not be there. Now when the official EVO froyo drops it will have the programming menu.
Hope this helps.
