Guys, pay attention to that update file. It is only updating modem.bin, and then updating your version number so you don't get nagged for an update. There are many more patches/updates in this fix than just modem.bin, and by doing only modem.bin you make it a bit more difficult on yourself to update down the road.
If that's all you want, go ahead and use it, but in no way did JT intend for this to get distributed as "this is what you should use if you have root" update.
Read before using, that's all I ask.
