EDIT: you have to download the SMSconversation.zip from one of my posts above too. ^^

EDIT2: there's a small bug (or feature xD) which moves the contact's bubble to the left while beeing clicked - sms_css.zip will fix that.
(so download the first file only if you want to have a look at the bubble moving around when beeing clicked ^^)
