Since yesterday's announcements at WWDC, it seems that third parties are now happily announcing applications for iPhone.
A lot of people here on AN must have their own favourite mobile app that they'd like to see for it.
I thought this thread could be a good place to list any announcements/links to 3rd party apps ahead of the official App Store release.
Don't list links to jailbroken iPhone applications, only list "Kosher" releases.
To get started:
First App:
SplashID for iPhone has been announced. I use this on my WinMo phone all the time for storing passwords/serial numbers etc.
Second App:
TomTom satnav. Reuters confirmed it's existence but TomTom have yet to announce a release date.
