The next time you boot up your PS Vita and attempt to connect online, you will be prompted to download the latest 2.05 firmware.
If you are wondering what features the new firmware will have, you will be disappointed as there are none. It seems that the new firmware is just another system stability patch. If you got away from not downloading the other patches that Sony released, which are optional, you will have to do it this time with the 2.05 firmware as it’s mandatory.
