Never listen to music on my iPhone, so was well chuffed when I realised I could download the PodCast of Couch to 5K on my iPhone (OK, it took me ages).
Also discovered you can buy a case thingy to wear on your arm, to keep it in, although people with thin arms don't find them much use................good, they should not be so slim, I know I won't have that problem........grins.
An added bonus if you use your iPhone, is the App Walk Watch, it's brilliant giving you all the stats, map of route etc and you do not have to have 3G on either.
