Sony Ericsson Xperia X10 :: Need To Un Root And Wipe Root Evidence

phones gone and broken itself, half the screen is white and its decided to not make calls and send texts, well sometimes works, mostly doesnt. regardless i need to unroot this thing and clear any proof it was rooted before it goes back to rogers. i used z4root to root it, can i do the same to un root and then do the software repair from pc companion to reinstall the software and get back all the things that were on the phone like timescape and such?
