Facebook have begun to roll out their new profile design: Timeline, to iPhone through the mobile optimized version of their website. The redesign features most of the important features of Timeline.
- Viewing and changing Cover Images.
- Scrolling back through time - from birth to the present day
Other features are missing, like the ability to add 'life events', or change the date of photos to have them listed accurately in your timeline, but overall the interface is really nice.
The new timeline interface is only viewable on profiles that have enabled them on the normal website. Timeline hasn't rolled out on the iPad, or the native app, but no doubt it will be soon.
