I've been using SportsTracker 2.6 for about a fortnight. My iPhone addicted partner is utterly envious. Apparently, there is no comparable background app for the iPhone. She claims that Apple won't permit developers to release background apps. Who knows! It's another reason I love my N95.
The iPhone just can't multitask. That's why there are no background apps.
It is a version of OS X and there are multiple background tasks already. It is just not allowed for applications.
Some examples are: the music player, email polling and downloading of applications in the background.

Read my Blog: http://www.pietschandfriends.de - All about Sports&Training and technical gadgets,
iPhone users can just get the MapMyRun application from that site. So I doubt they'd be that envious.
