Same as mos and frogstomp. Bought the DVD for my shonky N95, then, when the iPhone app appeared I bought that and loaded half the UK onto the phone, from just north of Birmingham down, plus selected area of 1:25k. I also have UK Map, which is very good, it allows you to download free 1:25k and 1:10k OS maps, but there’s no ability to log routes. Very useful though. I’ve got 11.2Gb of apps on my phone, and a very large chunk of that is maps, with CoPilot added on. Wouldn’t be without it, it’s fantastic. I’d like the old panorama view added sometime, though.
