I'm having a pretty big problem with the iPhone 3GS and Nike+. Most of the time (thought, not every time) when I get close to my second mile the iPhone starts to automatically going to voice control or pausing the workout. As soon as I resume the workout or cancel Voice Control it immediately goes back to one action or the other making it nearly impossible to finish the workout. I thought it might be the Apple headphones (and I'm still not totally convinced it's not), but I exchanged them with Apple and I'm still having the problem. I'm not really expecting anyone to have a solution for this, but I did want to try and see if this is a bug on my specific iPhone or if anyone else was having the problem. Thanks!
