Facebook has revealed that an upgraded versions of its website has been out. At present Facebook has two websites like m.facebook.com and touch.facebook.com for touch based smartphones like iDevice.
According to Lee Byron, Head of mobile products at Facebook :
“Every time we launched a new feature, we had to build it multiple times across different code bases: once for facebook.com, then again for m.facebook.com, touch.facebook.com, and in native applications as well. Honestly, we weren’t very good at doing this, so certain features were missing on different devices.”
