Sony Mobile has sent out invites for an event in September 4th in Berlin, Germany. This event is said, according to rumors, to unveil the Xperia i1 which has been circulating the rumor mill itself. Anyway, the interesting thing here is that, the said event will happen at exactly the same day Samsung has set for their Samsung Unpacked Event Episode 2. Sony's event will happen 2 hours before Samsung's which will start at 7PM (local time - Berlin). As usual though, IFA Berlin is always a time where a lot of new gadgets are introduced to the world so this does not really come as a surprise. Let us just be ready for September for it is just around the corner.
