For once I feel sorry for iPhone owners, especially if they buy TomTom. They know nothing of customer loyalty and will quite happily charge you full price for software updates where as all the other companies I buy software from will offer you a discount for an upgrade (MS included), may seem trivial but when your paying £70+ for maps each time!
I don't have an iPhone but after a few years of being financially abused by TomTom I ditched them and went with CoPilot as version 8 of their software is definately worthy of what I'd paid for the TomTom product but thankully CoPilot don't charge that much and if you have a HTC phone with version 7 installed (which obviously comes for free) they will still let you have a discount when upgrading to version 8, happy days, even happier that I could take all my custom favourites and POIs with me as well.
CoPilot you will have my money for a number of years if you keep that attitude, TomTom you can get stuffed.
Paris....errrrr..... ummm, cause she gets about a bit.
