ICQ owner Mail.ru has announced that they are developing a native app for the Windows Phone platform and it would soon be available from the Windows Phone Marketplace!
ICQ is one of the oldest instant messaging platforms that still exist and it still has around 100 million accounts.
It is not clear however how many of these accounts are actively used today.
A lot of us who have been online for more than a decade are likely to have an account on this network. We would only find out how many of the active users are actually using a Windows Phone platform once the app launches.
