Facebook announced today that it had altered its Facebook Messenger app to allow users to create Messenger accounts with only a name and a phone number. The alteration brings Facebook Messenger into the company of other SMS-replacement apps such as WhatsApp and Handcent, as users can now message contacts with just a phone number, as well as share photos with them. The social network rolled out the update to its Messenger app for Android today, and will be rolling out Messenger accounts over the next few weeks.
