What is the difference between the windows mobile 6.0 and 6.1?

There are a few differences between Windows Mobile 6.0 and 6.1, the most noticeable being:

- The texting application is now displayed in a more modern, conversation-like form
- There are performance and efficiency improvements, some of which you might not ever see
- The OS is preloaded with new music
- In many devices, there will be an interface change on the home screen. With HTC touch screen devices, it might come with an optional grid-like plugin for the Today Screen (home screen), allowing you to more efficiently manage information. On non-touchscreen devices, a modern new interface called "Titanium" is implemented on the Today Screen (home screen), allowing for sleek content organization.
- On some phones, functionality is improved. An example is the AT&T Tilt, receiving the once absent feature of PTT or Push To Talk
- An over all improve on menu/inbox performance

There are many more changes between the two OS's. If you have any questions, email me at gustavoser@hotmail.com, as I myself upgraded my AT&T Tilt from 6.0 to 6.1.
