Plus XP: Nintendo Letter Box

HelenBaby from Plus XP writes: "Nintendo Letter Box (known as Swapnote in America) is the latest free application to hit the 3DS eShop. It is intended to act as an email system of sorts, where users can exchange messages with other 3DS users either via Spotpass (aka online) or broadcast a message via Streetpass (where players exchange information with each other locally). It was released on the 22nd December, and is the sequel to the DS app Pictochat.. This article will firstly talk about how it feels to compose messages on Letter Box, then look at Playback, and lastly some thoughts on the communication aspects."
