They're also hiring....
As part of the work we've done for them, we ported an extended an AccordionView to MonoTouch - and they're very happy to contribute this back to the community.
You can play with this on https://github.com/slodge/MonoTouch.AccordionView
Hope you enjoy it.
If you spot any bugs or improvement, please do let us know :)
Somewhat shockingly... currently there are no bindings for MvvmCross - but hopefully one of us will add them soon :)
