The PSP2 will be supported by 3G connectivity, but won’t actually be able to make phone calls according to Nikkei (via Adriasang). Sony’s new handheld will have its 3G service provided by NTT DoCoMo in Japan, the country’s largest mobile network service.
The console will still have the wireless LAN capabilities of the original PSP, but the 3G alternative will offer a stable and permanent connection for downloads and online gaming. The new handheld will also supposedly have an OLED screen and a custom built processor capable of handling high res visuals.
Stay tuned for more info.
