I'm considering dumping my Iphone for an HTC incredible. I travel to Singapore once a year. In the past it has been very useful that I was able to use my Iphone as a GPS. AT&T allows you to pre-pay for international data and I was able to use google maps and check my email etc. I don't really care abou the email because I can always get on a WiFi, but the google maps wouldn't have worked and I really loved having the phone as a GPS. Anyway I'd like to continue to have that capability. I was wondering if it is possible to download a map of an area while on WiFi and then use that for road directions later. The phone also doesn't matter because I have an old unlocked Nokia phone and I'll just buy a local pay as you go number. Although I guess I could do the same with my portable GPS but they charge 120 for a map of the area.
