As discussed before here, Sony have now (finally) released the new PSP-Lite firmware (v3.90) which includes Skype support. You additionally need the PSP Skype Headset. This offers a full Skype experience, including SkypeIN and SkypeOUT. It is currently only available via the Network Update facility direct on the device, but a PC download option should appear soon.
A lot of people have been trying to connect their TomTom SatNav devices to their new 3 SkypePhones to get traffic updates, and having problems. Crundy, who developed the SkypeIN / SkypeOUT workaround, has released details instructions on how to achieve this, which you can access in the rest of the article.
Sony have confirmed that Skype will be coming to the PSP-Slim via a firmware update later this month, but that it will not be available on the original PSP.
The Skype functionality includes SkypeIN and SkypeOUT though, which the 3 Skypephone doesn’t have.
Crundy, a user on the 3 SkypePhone forums, has created a PC application to get around the lack of SkypeIN / SkypeOUT on the 3 SkypePhone itself.
