When you say "nothing happens at all", what do you mean? Is it stuck 
in the IAP code or did it cause an exception?

There are a few things that I can think of that might be causing 
problems:
* Incorrect set up of parameters. Likely to cause a data abort.
* Incorrect set up of the thumb bx stuff. Likely to cause a prefetch 
or other abort.
