The "new" app will work on ANY (to my knowledge) rooted device running Android 4.0+ and allows you to set the limits yourself (within reason). Basically, just load it up, set your limits, click apply, and reboot. The settings will stick unless you wipe data or factory reset your device and I included an option to return to defaults if need be.
There is a known problem with the reboot binary on some HTC devices not playing well, so you may have to reboot manually. Please let me know if you encounter any other problems with it and I'll work through them.
You can grab the apk from HERE. There is an identical donate version available from the market if you're feeling generous.
