Samsung’s been teasing us all month about a secret mobile launch, complete with count down clock. But the wait is over. Tonight, the phone will be unveiled in three launch locations around the world, Dubai, Singapore and London. The mobile’s been kept under wraps, as far as we know, and the usual internet rumour murmers have been rather quiet on this one. Smart money is on the I7500, Samsung’s Android-running handset, or a new mobile running an updated version of Sammy’s TouchWiz OS. We’ll be at the event later tonight, more news when we have it.
