HTC UK Event April 12th
HTC have just sent invites out to a press event in the UK on April 12. The invite image has some sort of liquid feel to it, but its hard to see if this fits in with what tehy could announce.
Its likely that HTC will use this event to announce one or all of the following android devices, including the HTC Pyramid, the HTC Evo 3D and the HTC Flyer. They could also announce a yet unknown android device (it could also be Win7 related, but this would be #uberlame). We'll be sure to update you on the details of this when it happens.
