A few weeks ago, our colleagues at WABetaInfo discovered a brand new feature, as usual, in the beta version of the app that lets you send messages to yourself. Finally got it wait a month before we see it arrive on our smartphones. You used to be able to chat with yourself by creating a group of which you are the only member, but this feature makes things much easier.
The Message Yourself feature gives you access to a chat that only you can see. You can send messages here, as in any other chat. You can also use it to write important notes to yourself, save web links, or download documents and voice memos.
