the sim-free xZ come with Chrome as default,
some people prefer the normal android browser (I Like both, so use this and chrome beta )
it does have some features that chrome doesn't such as full-screen and quick-controls.
to install : You will need ROOT !
on an unbranded rom, you will need to remove
otherwise you could get issues with conflicting package names.
then push this to system/app and chmod to 644
Appears you need chromebookmarksyncadaptor as well to get synced bookmarks
cheers r1c4rd0 for that
