Sprint today officially (albeit quietly) took the wraps off their branding for their WiMAX service, Xohm. Sprint provided few details other than the logo, and an official launch date of Spring 2008. The web site however fails to mention test markets which are still expected to launch at the end of this year. Sprint is touting WiMAX as the future of wireless data, and providing a list of examples of how WiMAX service will change people’s lives.
