Seen two apps on Google Play regarding Odesk but can't say which one is from Official Odesk. We both should wait for some official reply.
Don't use until official confirmation as some peoples create apps to steal passwords / personal data etc.
Waiting for some MOD reply here please.
Even if it is an official oDesk app, the likely train of events would be for lots of people to ask about it on here, until there is eventually an official response saying "we are looking into ways of announcing the dertails of this...).
