Yea, I've done quite a bit of modding to my V3i, monsterflashing isn't that big of a deal, as long as it's done properly. However I try not to do it, since it overwrites all of the settings (just as a flex would). Keep in mind that the V3x may have some methods different from the V3 and V3i. My personal favorite resource for Motorola modding is the forum at
