Didn't have too many issues with the 3G in my car, but it is mounted to the air vents right under the windscreen which may help. When I borrowed a Transit (Luton) the other week, getting the phones GPS to work involved having the passenger hold it against the window as it couldn't get a signal inside the cab. I'd have probably been fine if I'd remembered to pick up the windscreen mount out of the house before dashing off. Luckily it was only a 1/2hr run up the road & knew my way back without it. -- Jon B Above email address IS valid. <http://www.bramley-computers.co.uk/> Apple Laptop Repairs.

Her newer one is better. Mine is next to perfect, and is as good as my tom-tom 710, and better than her tom-tom home.

But that is ultimately a flaw of indesign that it is not good at editing text. Although there is no equivilent for the iPad, a sensible approach to do that would be to have an edit option for text that sent the text to a decent editor, and recieved the result. -- Woody www.alienrat.com

Yup, as I said. With the additional benefit that A-GPS brings which is that the GPS fix is faster as it gets the satellite position info quicker. Even over GPRS it's many times quicker than downloading that same data over the GPS link (which is an exceptionally slow data link by today's standards). > WiFi would give it more information but I usually have that turned > off. The satellite position data is so small that I doubt you'd see a difference between WiFi and cellular data. If you had no cellular network connectivity a fix should take longer (up to a couple of minutes) but you can't test that with the iPhone before iOS4 as GPS is turned off if you turn airplane mode on. I don't know if this works differently with the dedicated switch in iOS4 that turns off cellular data. -z- -- email: nettid1 at fastmail dot fm

Sorry I wasn't too clear - CoPilot isn't working with the iPhone's receiver at all - the dish icon blinks but never gets a fix. It works really well with the TomTom GPS chip built into the cradle, but unplug the cradle and CoPilot goes back to 'Determining Current Position' Stuart -- cut that out to reply |
