Hi Seoirse, I also purchased an ifone recently. I am with vodafone Ireland and am a bill pay customer, I waited until the new ifone 5s came out in October. The phone is 650euros but as a bill pay customer I was able to purchase it as an upgrade for only 100euros. As for navagation the voice over helps but there is also siri which is an in built personal assistant so you can ask him things like set timer for 20mins or call John etc etc. However it does take getting used to and if it wasnt for the vip list I would be harassing my vodafone store!!! Best wishes Aine Mae
