Great, thank you
Also, just a quick note (which is probably too late) ... for those who want to test their environments to see if the upgrade is going to mess with anything, they can get http://www.wampserver.com . Do a full backup (database & ftp) of your site, and restore it under the wampserver environment. As wampserver comes with the latest php & mysql versions, you will be able to test on your pc what will be the impact of the upgrade, and fix them prior the host upgrade occurs.
Just thought this might help in case there is anyone who hasn't been upgraded yet
