Verizon Wireless began offering Ringback Tones -- short clips of real music that replace the standard ring callers hear when they call the Verizon Wireless phone of a Ringback Tone subscriber. Customers can browse from an initial catalog of more than 2,200 songs in 13 different music genres to selects tones that can be associated with different callers based on the Caller ID, Group List or the time of day. The service is initially available in parts of California for a monthly fee of $0.99 per month. Each ringback tone purchased is $1.99, which provides unlimited use for one year. Both the monthly fee and cost for each tone appear on the customer's monthly bill. http://www.verizonwireless.com/
