Google is holding an event this week on August 12.
Not much is known about the event other than it being related to Google Mobile in that they announce that they are “unveiling a couple of cool new mobile features”.
We’ll keep an eye on the details. It’s only a couple of days away, so there isn’t too much time to wait now.
Gizmodo point out that Google Maps Navigation was announced at a similar event, so perhaps something along the lines of a new service for Android based smartphones will be unveiled.
