I just picked up the phone yesterday and love many things about it however I do not like the look of the UI at all, it looks very amateurish and "cheap". I know there are many themes available out there but do they work on this phone? Does it require a custom ROM? I assume it needs to be rooted to get a custom theme, right? I want something that will change the look of every screen...dial pad, text messages, menus, settings. Imam really not liking the white text on black background.
