Twitter just made announcement that they have refreshed the user experience for people using their service on feature phones. We know that Twitter recently rolled out the new form but it was mostly limited to certain browsers like Android Browser which is based on WebKit and surprisingly even the mobile IE9 was excluded from the list.
Twitter team has worked to extend the same rich user experience to the browsers on feature phones. The looks and functionality is similar not same. For those seeing it for the first time Twitter has even provided the quick guide. For the sake of comparison, we’ve added couple of screenshots of Twitter on Android Browser and Dolphin Browser on bada OS.
