Remember this, future iPhone 3G users in the UK: turn off the "Data Roaming" setting on your handset when traveling abroad! Why? Because O2 has gone overboard with its insane data-roaming charges. For every single megabyte you download, you'll be paying £3 (about US$6) when roaming around in the EU. Leave EU borders and the charge doubles... Don't forget it, and you're safe.
