Either roaming on AT&T is blocked for toggle SIM cards or they do roaming steering to force your phone to TMo despite the worse signal strength. If the latter is the case you should be able to force your phone onto AT&T by performing a manual network search and selecting AT&T. If this fails repeat the search and selection process
four times. If is still fails after the fourth attempt, you definitely can't roam on AT&T.

that said, I've been able to add value to the card, and will test in town tomorrow and confirm balance et al. (I have now turned off data so I don't pay while in the USA at the moment, although they may not have data but in the text I got it said boom your data will cost 4.70l per mb...ouch

As long as you haven't changed your iPhone's default settings it won't establish an Internet connection while it's on a roaming network anyway.

Does anyone know if I can sign up for UK data plans, so using the *141*7500# to sign up for a UK plan, but sign up while I'm in the USA? or does one have to do that only in the UK?

If USSD (those codes containing * and #) works out of the US, you will be able to activate a data bundle. You can find out if USSD works by dialing *131# which should display your current balance. If it fails USSD probably doesn't work on the selected roaming network. In that case you could try registering on another network and try it again.
