iOs & iOs Apps (inc iPhone, iPad, iPod, iBrick)

I bought this software after seeing a very good review of it on Register Hardware.

My early experiences of it were not great however- this is the email I ended up sending to their technical support:

Hi,
I've had a few issues with your software, could you help please?
To give you an example of a trip I took on Sunday after wiping and reloading my iPhone from iTunes and reinstalling Co-Pilot.

1. Start off- Co-Pilot crashes three times.
   
2. Co-Pilot finally loads, acquires GPS fix and starts navigating
   
3. Merging onto the M25 Co-Pilot loses the GPS fix and stops navigating
   
4. GPS fix reacquired, navigation starts again
   
5. GPS lost and re-found approx every 2 to 5 minutes- the time to re-find the GPS varies from a handful of seconds to 10 or so minutes.
   
6. Co-Pilot crashes again
   
7. Arrive at destination after pulling over and looking at map
   So- at the moment it is worse than useless as a SatNav and I am very disappointed- it is impossible to trust Co-Pilot as it crashes and loses the GPS fix so often.
   (I have an iPhone 3G)
   Kind regards,
   Me

   Sadly they ignored my email until today, when I finally got through to a tech support person.
   They apologised for ignoring my email, and then went on to say that they had had "lots of the same complaint from iPhone users".
   Apparently the GPS chip in the iPhone is just not good enough, causing some but not all of the faults I found.
   ALK Technologies (who wrote CoPilot) asked me to do the following:
   ------------------------------------------------
   Thank you for contacting CoPilot Technical Support.
   The GPS receiver inside the iPhone isn't as good as many of the newer GPS Receivers on the market and does need to have a very good clear view of the sky and not be obstructed at all by UV coated windscreens.
   If you do not have a 3G connection or have disabled your 3G / Data Roaming then you will need to stand outside for approx 30 mins with a clear view of a sky (not in a car) to get your first GPS fix. After this it will be quicker to get a GPS Fix.
   Please note if you have put your phone into AIRPLANE mode then this will turn off the GPS Receiver.
   Another way to jump start it would be to check to see if you have a GPS fix in Google Maps. Launch Google Maps and see if it snaps to your current location. You should see a dot showing exactly where you are with a pulsating circle. If the circle isn't pulsating or the location is elsewhere it's because your GPS Receiver in the iPhone doesn't have a fix.
   If you have any further questions, or feel that this incident has not been resolved to your satisfaction, please do not hesitate to bring this to our attention.
   Regards,

   Now I can do all of that bar replacing my windscreen, but the question I have is this- to me it seems as though the iPhone cannot actually support the software due to a rubbish GPS chip, therefore should ALK be selling this product at all?
