June may not officially be summer for everyone, but it is definitely the hot month for cellphones! With the Samsung i8190 Omnia HD and the Nokia N97 scheduled to hit the market in the coming week, the Apple Worldwide Developer’s Conference and Samsung’s Unpacking event, June is the month for smartphone madness.

Who is the newest to get into the chaos? Well, that is our favorite smartphone manufacturer HTC, that is. They are having a soirrée and it’s planned for June 24th. Like the brands above they are planning the release of a new model which will likely turn some heads. Only a year ago HTC was using similar promotional devices to launch the new Touch Diamond.

Most people are speculating that the device will be the new HTC Hero. This a model that will be running the new Google Android release, code named “Rosie.” We haven’t heard much solid rumor on this yet, but we we’re willing to put a penny on that one.

The “Rosie” beta build recently appeared on video being run off of an HTC G1. The interface looks impressive, although a bit stuttering at times. However once it is complete and running off of the Hero we imagine that it will look even better.

Here’s to June, the month that launched a thousand smartphones.
