There are times you would want to use/
operate two social accounts on your
Android phone, but it seems impossible,
because you need to sign out one
account for the other. Though, Twitter
and Instagram Apps has this feature to
login two different accounts at the same
time on the app, but other Apps like
Facebook, BBM, Whatsapp etc are yet
to integrate this feature.
Today, i will be teaching you how to run
multiple social accounts on one phone
without the need to root your Android
device. There are other free apps on
Google Playstore which offers same job,
like Parallel. It helps you run two
Whatsapp accounts on one phone, two
Facebook accounts, two BBM accounts
on one phone, etc.
I will be introducing you to a new App
that does same job as Parallel.
