According to a sneak peak of the March issue of Playstation Magazine an email client will be included in an upcoming firmware update.
The built-in email program, called Sony Mail, will use the unique ID number assigned to each PSP at manufacture to eliminate a potentially confusing server setup. The program won?t require users to access a web site, but will let them choose a unique user name to associate with their PSP?s ID.
Also, Sony will release its GPS (global positioning system) add-on for PSP later on in the year. The yet-to-be-priced package will include the actual GPS peripheral, which connects to the top of the PSP via the USB 2.0 port, and a UMD containing navigation software and street data.
