For those willing to get Iphone app. I'm not sure that's smth that BBs should try to do. Not sure if some of developers even knows how to create Iphone app. If there is some user having ideas how to create this - just contact BBs, I believe you could be rewarded by Supporter for example.
Again:
third-party software is called so, because it is third-party, not the developer's.
