Radio options in build.prop
I decided to post this after doing some research and putting off testing this for a while now. I know editing the radio options in the build.prop has been tossed around as a whisper in dark hallways for a while now but no one has really seemed to do it and see what happens. This is just for the Slide in America, I have no clue if it will work in europe, though I've heard it does.
All I've done is edit the following lines:
Editing the wifi scan interval should save on battery (it's set at 60s now instead of 15s), the 3G prefix is 0 by default and I think it's just asthetic even though I haven't noticed it yet. There are 2 ro.ril.gprsclass listings and usually they are different classes, I set them both to the same class. Lastly, the wifi channels were (on my rom at least) set to "blank" and I figured that might be an issue for some of the roms that have trouble with wifi so I set that 14.
I won't say that this will increase your speed or help lock on to 'H' or '3G' more, you'll just have to test it for yourself and see if you notice anything. If enough people do try this I'll put up a poll to see if editing the class or wifi settings actually helps.
Back up your original before you push this (of course you're in recovery).
adb pull /system/build.prop <path to where ever>
Then to push it:
adb push <path to new file> /system/
I'm not taking credit for this, I'm sure I'm not the first or last to do this
