I don’t usually bother upgrading the OS on my phone the day it comes out because usually I am too busy. I don’t, however, usually avoid doing it for long but on this occasion, I am going to have to.

Apple have replaced Google Maps with some homefried application of its own. It’s fair to say that according to most of the comments about it yesterday, it probably isn’t very useful.

My most frequently used applications on my phone are the browser, the phone, text messaging and maps. On my iPad it is probably the browser, Chilltrax, Bejewelled and the maps. In real terms, I can’t actually do without the maps. They find me when I am lost. They cover me for everywhere I have tended to need maps. I have been standing lost in the middle of Helsinki finding my way to my hotel using maps on my phone. I have used maps on my iPad to plan journeys in France and check out areas where I dream of buying houses. They regularly help me locate myself in the banditland that is anywhere south of the Liffey. Last night they helped me find Dunsink Observatory.

But it doesn’t sound like I can rely on the same accuracy from the current incarnation of Apple’s maps product so for now, no iOS6.0.
