Chalk another MVNO up for Obopay: After announcing an expected deal with Amp'd Mobile, Obopay has signed one with MVNO Helio for its mobile payments service. Just like the Amp'd offering, Obopay will enable Helio subscribers to use its "real-time, secure, mobile peer-to-peer payment service, which is linked to an Obopay Prepaid MasterCard account." The service allows users to check balances, view payment histories, add funds and more.
