[XPERIA X10 Android Development] cobrato:
This rom is based on MIUI Android Nexus 1 version - http://miuiandroid.com/

It is still in beta, so flash it at your own risk :)

I did this for the lock screen only. It's really cool

The update will not erase your data. But please backup just in case

1.7.8 onwards uses a new theme format which is faster to apply. Themes with old format will need to be converted which can take some time.

you can get the change log and subsequent updates from the official site.

Some FAQ here so please don't repeat the questions :)

Q. Camera / Video not working?

A. Camera / Video works only with Camera Illusion & Videocam Illusion @ 800 x 480. That's the limitation of current GB rom. You can use dualboot to resolve the issue:

Q. Screen rotation very laggy?

A. It's due to the theme. It's mostly gone now with later releases

Q: Rom wlod frequently ?

A: It could be kernel related. Please try the stable zKernel or Stock Kernel to confirm the issue (post #2)

Q: How to enable dualboot?

A: Pls follow riginal's guide here: http://xdaforums.com/showpost.php?p=15278207&postcount=666

Q: How to enable App2SD?

A: Your SD Card must be in single partition FAT32 and apps that support app2sd (eg Angry Birds) can be moved to SD Card

Q: Why my Miui Music Freeze?

A: Miui Music is still buggy. You can work around by setting equalizer to flat and then disable it (thanks kaosdroid). Or use another player and set it as default.

Q: Why my battery drain very fast?

A: You can try some battery calibration method or change kernel or change baseband (eg bb58 works wonder for DaveHTC200)
