Loads of apps missing in Market on new phone

[mmace]

Evening!
My wife has just got rid of her faulty X10 and moved to the X10 mini pro

She's very frustrated as apps are just not showing up in the market. She used Bloo all the time along with AG Newspapers UK and Flood-it (game), these were 3 of the most used apps she had but when she searches the market for them it says they are not there!

I have managed to get hold of the latest Bloo beta apk and installed that and it works fine.

Any ideas why these apps do not show up?
the mini pro is 320x240 so it's not a resolution problem (same res as my old G1), the apps show up on my Desire (same phone network etc)
the phone was unbranded/unlocked from Expansys

Any help appreciated!

The first (and only, really) thing that comes to my mind is that she's now on a different version of the operating system - one that isn't supported by some of the apps.

it's 1.6, same as the X10
