Hi, I have a quick question regarding getting custom (non-itunes store purchased) ringtones to work on an iOS 5 iPhone 4 that doesn't sync with a computer. Previously, I would have done this by obtaining an M4R file, placing it in the Ringtones folder for iTunes to see and syncing my iPhone with my Computer and therefore transferring it. However, with the arrival of iOS 5 and iTunes match last year, I have no reason to sync my iPhone with my computer. How do I now get custom M4R files as ringtones on my iPhone? Thanks in advance for any help!
