Mobile operator Alltel and online personalized radio service Pandora have teamed on an online marketing campaign that invites Alltel customers to submit their favorite hometown bands to Pandora. The result will be Alltel Wireless-branded local music stations on the Pandora network.

Pandora's registration process captures users' zip codes, so Alltel can take advantage of precise geo-targeting to market its "My Circle" message.

Alltel is the exclusive advertiser for the three-pronged yearlong campaign. In phase one, consumers can submit their favorite local bands for possible inclusion. Phase two involves the companies going through all the submissions and creating the branded local stations. Finally, in phase three, the stations will go live on Pandora.

What we find most interesting is that there's no mention on Pandora's Web site that Alltel offers its mobile service, just AT&T and Sprint are listed.
