co ordinates?

[stevierst]

numpty question, if I use Google maps, do I have to have an internet connection or GPS turned on........obviously the more stuff switched on drains the battery or can it be done "off line" so to speak?

Afaik you have to switch on your 3G at least.
For it to be more accurate, you have to put your satellite setting on though, as the 3G location can be out by quite a bit.
