It's finally happened.
After months of pestering from the user community, Instagram has finally implemented an update that allows users to operate more than one account from their app.
Previously, users with more than one account (business/pleasure) had to sign out of one account before signing in with the other. Now the app falls in line with the likes of Twitter, allowing you to control more than one account from the app simultaneously.
Here's how to access the new account feature.
