Vita And PSP Activation Limit Will Be Increased After PSN Maintanance On December 9th

A planned five-hour maintenance period will help improve the user experience of PlayStation handheld owners including the PlayStation Vita on Monday.

The maintenance will start at 5 p.m. ET on Monday and users will be able to use their games and apps except for the PlayStation Store, Account Management or PlayStation Home.

As part of the improvements, Sony will increase the allowed device to connect to a single PSN account from two to three. This applies to both the PS Vita and the PSP.
