[OSM-newbies] new to OSM editing - advice on coping with gpx / POTLATCH offset

[JW]

Hi all

I started small by adding some .gpx data 
(Blackberry curve / bbtracker.org app)
to local maps in areas which i know well.    
This area has been mapped
previously by someone using potlatch and the 
yahoo available satellite photos (UK)

It turns out that there seems to be an 
offset between potlatch  locations and
.gpx data i record - maybe 5 to 10m or so.


There are a few courses of action

1) trust my phone gps .gpx data is correct 
and change all potlatch locations as
i can..... this is not practical for 
a small edit added to a large mapped area

2) don't worry about it this is 
within normal gps errors ..... just "interpret"
where the footpath is and add it beside the potlatch road.

3) something else?

What do others do?

Ciao
