I recently switched to Verizon from AT&T. I had an iphone and am now using an old KRZR until the new iphone comes out and then I will upgrade. But, I will probably be using this thing for 3 months or more so I wanted to try to put some ringtones on it. My computer doesn't seem to detect it. I even downloaded Motorola Phone Tools which is what I used on the KRZR i had back in 2007 but even though it acts like it detects the phone it will then say that it doesn't. What am I to do???
