Android 2.3 Keyboard on SE X8 running 2.1 Recently I've found out that it's possible to install new Android keyboard on 2.2 version of Android (here's the installer).

I was wondering if the same applies for 2.1?

I own SE X8 which I've recently updated to 2.1.
The 2.3 keyboard cannot be installed on 2.1 as-is.  It relies on the 2.3 Voice Search app, which uses API methods not present in 2.1.  (See this XDA post.)  I'm sure someone is in the process of hacking the keyboard to work though.  To be honest, the only difference I see with the 2.3 keyboard is that the keys are smaller, which I dislike.
