Hi, I'm about to travel to China from the UK. I have an HTC Desire running Froyo on Vodafone and am wondering about charges that might accrue to my account should I leave the settings unaltered. I subscribe to a couple of news feeds and weather channels which I think access the internet for periodic updates, as well as email. I don't want to rack up huge costs whilst I am away so how could/should I alter the phone's settings to ensure that I keep costs to a minimum? Obviously I'm happy for the phone to connect to open wireless networks in buildings and offices, it's just where there is no network the phone currently uses the mobile network to access the web. Any help much appreciated.
