I don't believe apple holds any sort of claim to i product names. Witness the Cisco iPhone.
Also, iRiver came about in 1999. At the time Apple was a small company that had minor first release product called an iMac. iPod and iTunes came out a couple years later. Any real recognition of i product names and Apple came about later.
