Forget MySpace on Helio, Facebook is going after the big guns: the popular social networking service is going mobile with  Cingular, Sprint Nextel and Verizon Wireless. These operators are starting a service that will make it possible for users to post messages on Facebook’s home pages or search for other users’ phone numbers and email addresses from a cellphone.
Yesterday Facebook’s new mobile services were launched at Harvard University, Stanford University and the UC Berkeley. They will be available to students at more than 2,000 universities by the end of this month and high-school users of Facebook by early May, the company says. Any SMS-enabled phones can support the new Facebook services; students don’t have to download special software or pay extra, though they may pay more total fees for data usage if they send more text messages.
A competing mobile social neworking service Rabble is already on Verizon and Cingular, so I am assuming this is not an exclusive deal.
On Helio-MySpace, Helio says it will require MySpace users to affirm that they’re 18 years or older when signing in, to do away with predator worries.
