Ah thanks very much Sam! Also thanks Rikki and others for the welcome, glad to be of service. :]

I know it's probably a stupid question but what do others find is the most reliable/accurate GPS to use for mapping? The reason being is I have made quite a few traces on my walks to work each morning, and some will be quite a bit off whereas others seem to be roughly on par with where the previous track(s) were. I'm sure i will find the information eventually but i welcome anyone's input/tips/tricks with it.

Now corrected, lesson learnt. Now time to carry on with the original idea (Strap iphone to the bike!) :] I have only left the roads i put in originally from my own GPX data.

Ah parden didn't realize! I shall go and correct the mistake, apologies! :S
