Well actually it does not matter if its not PHP 5.3.9, she should be able to get her site running with just PHP 5.3.0. Of course there may be some errors initially, but they are easy to fix. You may give a try on Nemesis' hosting package, its running PHP 5.3.8 but fixing the issue wont be a headache. If the PHP version is 5.2.x or below however, the game is over.

Just asking now - Would http://byethost.com be a better host?

Right now it's the only remaining option for me..

They seem to be providing PHP 5.3, which is good. I am not sure for PDO though, chances are it is available. But anyway, it wont hurt to try it out yourself since they offer freehost services. After releasing Mys v1.3.3 I will probably take a look at these freehosts myself and prepare a list for users of this script.

Trying it out right now, and thank you SO MUCH for being such a nice and interested admin ^^ I think future members would greatly appreciate such a list.

Oh no worries, I am always glad to see members get the script to work. Lemme know if that host works out for you.
