You can use P2kCommander to add and delete ringtones to your phone. P2kCommander is free, MPT, if you want that you have to buy it. Also it dosen't support the KRZR yet. You will need P2k(http://s5vi.vxxxstuff.com/commander) and Motorola Software Update (http://direct.motorola.com/hellomoto/motosupport/source/SoftwareUpdateSelect).If you want to use this method respond back, cause I dont feel like typing this all in if your not going to it. I just got done doing mine, Ideleted all the Stock ringtones and pictuers and put in my own. Now I'm trying to figure out how to add my java games. Let me know, Jimmy
