A new firmware for the T-Display is now available here
There have been some exciting improvements, like:
much better stand-by power consumption. (over 11 hours on a 650mAh lithium)
better use of the screen (more text now displayed), revamped color scheme, and touch-optimised screens.
New 'Map View'! The home screen now has 2 tabs for switching between List View and Map View. You can also see locations of your contacts, displayed live!
Support for 'Post Office' message queueing, if recipient is offline or not reachable. (requires a dedicated repeater, and Ripple Commander Android app for admin).
Here are some of the new/updated screens:
the new home screen, in the List View
the new home screen, in the Map View
the new conversation screen. The orange dots next to messages mean it was queued in the Post Office repeater (recipient is offline)
the various settings screens now optimised for touch.
