Google has expanded the reach of Gmail Tasks to include the iPhone, Android or any other XHTML-enabled platform. The mobile version provides an interface that has been optimized for the lower resolution and size of smaller screens. Users can access the lists by navigating to gmail.com/tasks from the handset browser, where entries can then be added, edited or checked off. The service automatically syncs with the version of Tasks in Gmail Labs.

Tasks is available as an optimized version for the iPhone and Android devices, with full support for adding, editing and marking entries. The basic version, for XHTML-compatible handsets, only allows users to view the lists, add new tasks or mark tasks as completed.
