Just bought this phone, and it came with a USB cord but no installation disk! I searched it up on the Internet and finally downloaded something called 'Motorola Tools.' When I plug my USB to my computer that's connected to my phone, it says it can't detect my phone! I then took my old phone and used bluetooth to send songs from my old phone to my new phone... but then I realized I can't set them as my ringtones! Question: 1. How come my installation thing can't detect my phone? 2. How do I make it so I can set my own ringtones for my Motorazr2 V9?!?! Thanks a lot!
