I plan on going to the States next year (I'm in the UK) for Comic-Con and I'd like to be able to use maps with the Desire HD. So, firstly I gues I'm going to need some sort of pay as you go data plan, and download the US maps, some how. Can anyone recommend a PAYG plan, if there is one, that has inclusive data? If there is one. Or even a PAYG that has the cheapest data. The hotel has included WiFi but on the road, that won't be much good. I'm not even sure I'll be able to access the US maps as I don't even have my handset yet, just doing a bit of research.
