The phones with built in GPS have inferior performance to a GPS mouse. This is VERY visible in town, and visible outside towns.
I use a N81 with whereami and a BT mouse currently ,this is the only solution that comes close to your proposal with good track accuracy (and not by averaging) and enough reliability to survive more then 5 minutes ( 3-4 hours is no problem) without crash. I have tried most available solutions but none functions reliable. Phones with built-in GPS will do nice in a autoroute application but will Fail dramatically in accuracy if you have to actually draw roads. I have bad experiences with N95 E90 (nokia) and HP 6500 series.

A user could survey their walk using an N95 or similar, and then, using a very simple interface, select whether they are on a footpath, bridleway, unclassified road, track, etc every time the type of path or road they are on changes. So if they're on a road, then turn off down a footpath, they could select "footpath". Then if the footpath merges into a bridleway, they could select "bridleway". The result would be a GPS track with sections "tagged" with footpath, bridleway etc. A track simplification algorithm could be applied and ways generated from the GPS trace automiatically. This could then be uploaded to OSM for a more expert user (who could subscribe to an RSS feed to inform them of such uploads in their area) to refine the way, i.e. remove extraneous points and connect the auto-generated way to existing ways. Any thoughts?
