Spears enters the phone age to connect with fans You've probably accepted by now that Britney Spears is never going to call, even if she actually had your number.That doesn't mean, however, that she won't leave you voicemail - for a price. For $19.99, you can purchase a three-month subscription to Britney's wireless fan club, which entitles you to "surprise" voice and text messages delivered right to a mailbox you can access from your mobile phone. It's the latest in the marketing of Brand Britney (didn't she used to be a singer?), this time under the guidance of WFX, a New York wireless network working to marry the latest technology and entertainment fads. Available for the past two months exclusively at Best Buy stores, Britney WFX will soon be stocked at other stores, says Jed Alpert, president of WFX. Fans who buy the Britney kit get kitschy goodies. They also get a phone card-size piece of plastic and an access code on the back that allows them to receive pre-recorded voice and text messages from the pre-packaged singer and her retinue.
