Tophat activation


I have read quite a few posts on the tophat installations but can't find any clear answers on what I am looking for.  I am wondering how long after the tophat has been installed will it be activated.  The tophat on our RIM was installed over a week ago and it seems as though work on it has finished(haven't seen anyone there for four or five days now).  The wholesale spreadsheet does show that activation is not due until the 30th of June, so just wondering whether we will have to wait until then or is there any chance it will be switched over to ADSL2 before then.  Also as I am currently with Telstra will the changeover be automatic or will I have to ring Telstra to upgrade to higher speeds (hopefully).
