Further to their statement earlier in the yeat that they would be working together, Sony Computer Entertainment Europe and BT have unveiled Go!Messenger, a wireless communications package for the PSP, due for release in January 2008.

Utilising the very latest in IP technology, PSP users can now keep in touch with each other, for free, from any wireless broadband internet connection.

By downloading an application provided as part of a future firmware upgrade, PSP owners will be able to instant message each other when connected via wi-fi using a new and intuitive on-screen keyboard.

By adding a headset, voice chat and voice messaging becomes possible, and by connecting Go!Cam, the attachable video camera for PSP, users also have the ability to make video calls to their friends and leave fun video and voice messages.

Go!Messenger has been developed in partnership with BT, through its 21st Century Network project, BT has enabled the PSP to be integrated with its current BT Broadband video and voice "softphone".

"With Go!Messenger, the PSP is pushing new boundaries, adding unique communication features to all the existing multimedia experiences," said Stephane Hareau, PSP European Marketing Manager.

"Enabling more than 8.5 Million PSP users across the SCEE region to communicate with each other, through video or voice chat, truly confirms the always evolving nature and potential of PSP."

Today also saw the official announcement of Go!Explore which gives the PSP GPS capabilities.
