Being a running fanatic you'd think I'd be delighted to hear the new iPhone 3GS handset has built in Nike+ functionality. Much like the iPod Touch 2nd Generation did last year.
Its just not something I would use. When I run its one of the only times I am away from my phone - away from calls, texts, emails and the web! I'll keep to running with Nike+ on my old Nano with Nike+ kit dongle pluged in.
Just to confirm, this new application in 3.0 does need the new handset (3GS).
