I have an Iphone developers company and we programm applications (cityguides) for Dutch municipalities.
Some of these councils want to have a symban or windows mobile version.
So actually an easy question.
We need people that can translate our iphone apps into aps for symbian and windows mobile handhelds.
(possibly even android and blackberry)
the Ibreda app in the itunes store is an example of the apps we build for Iphone
