marcellizot writes "PSP owners might want to sit down for this one: Sony has just signed a four-year deal with BT to turn the PSP into a phone. The partnership will add wireless broadband communication functions, including high quality video calls, voice calls and messaging. The partnership will initially integrate the PSP with BT Broadband's video and voice softphone VoIP software, meaning that calls will be free, with the customer only having to pay for the BT broadband subscription. This means that initially the service will only enable the PSP to communicate with products that run the softphone software. BT has already confirmed however that in the months following the service's debut, additional features will be launched to enable calls and messages to PCs, fixed lines and mobiles."
