that's great to see thanks. yes, i only read the clip from the OP and not the link.
If you had read the press release linked to in the first post you would have seen the magic words "iPhone 3G and 3G S owners will soon be able to upgrade their NAVIGON MobileNavigator software with another free update that brings additional features. " Note the word 'free'? That means you won't have to pay for it!
