Possibly you need to consider VPS. I have began using VPS for around last year and I am loving the liberty. It's a bit tricky at the start but bing is your friend :) Hope it assisted some.

I have been investing considerable time searching for an inexpensive hosting that is shared which supplies php5.3 support. Difficult to find.
Take a look at, they provide 5.3 like a beta - I'd opt for that. Their service is preferable to others, and they provide you with more access (ssh for example.) can also be using 5.3 already.
