Developer Arron La was able to test the most recent batch of Cupcake and make his own observations about the changes. According to him, there will be a new Notes and Global Time application, along with various other fixes. Since February is almost here, I wouldn't be surprised to find most of these coming to the G1 soon.
1. New Local Setting Page - Gives you option to pick different locales and pick different text inputs.
2. New Option to view running and third party applications - An option to view running and third party applications from the normal application list. Does not provide a way to terminate them.
3. New windows opening/closing animation effect - a new popping effect when windows are opened/closed.
4. New default notepad - a very simple and ugly default notepad.
5. New Global Time application - not sure if it will be provided by T-Mobile but it's just a rotating Earth and I couldn't get it to do anything else.
6. New Spare Parts Application - Once again not sure if the official version will have this, but it provides a number of extra settings such as setting windows animation and transition animation speed, font size, end button behavior and etc. It also has a "display rotation" option which supposedly should allow auto-rotate base on orientation across the entire os, but it is not currently working.
7. New Virtual Keyboard (as seen on video -ed.)- The virtual keyboard will pop up on every edit box. I didn't feel any haptic feedback but I am thinking that it's just not there on the example ke! yboard. Because the phone does not auto-rotate (an option exists but it doesn't work), it's very hard to type on it. The sample keyboard also does not provide auto-corrections.
8. Slightly better looking buttons with more shadow.
