Sony Ericsson has already confirmed that the Xperia X1, its new business focused mobile phone developed and created by HTC will be out sometime later in the year, but Handango, a mobile phone content shop seems to have the inside scoop on an actual date.

According to its latest partner newsletter sent out over the weekend:

"The Xperia X1 will launch mid-September 2008."

Handango issued the date alongside a call for content for the new handset.

"We are now seeking the best products for this device and we would be interested in hearing from YOU."

According to Handango, Sony Ericsson requires your product to support the WVGA screensize (800 x 480) and multiple languages.

We will keep you posted.
