OP says he will be creating a list.
The problem is this type of a file is usually ROM specific.
If you have flashed anything that modifies this file in any manner or if the Dev of the ROM you're using modifies this file, at all, then you're likely to receive boot loops.
OP said that the file post is for Myn's Rls 4 so it likely won't work on any other ROM.
With that all being said it seems like the Evo is NOT subject to this sort of Govenering.
As evidence by the multiple 30 GB / month users that can attest to it.
I feel inclined to point out that the amounts that you people suggest you use are the exact reasons why mobile providers are going to completely change the structure of their internet plans. [And I assure you it will be done server side]
There are four people on my plan.
Evo, Epic, Pre and Pro Touch 2.
Everyone uses their phones a lot, I use probably the most and we probably, all together use 2 GB a month. Likely much less.
I can understand using more once in a while...but 30 gb or more a month every month?
I'm sorry but that's clear abuse.
Why don't you guys just go sit outside Dan Hesse's house with signs that say "please get rid of unlimited internet" because that's exactly what you're doing.
It would be different if you purchase a mobile card and use that much data on that because that's what they're for.
The unlimited data for your phone is meant just for that...your phone.
