Hello, I'm in the US right now (I live in the UK) with my iPhone. I just got a text to say that I've used £20 of data since I've been here. Now: Data Roaming is turned off on my phone (I've checked several times), I've never turned it on. Whenever I've picked the phone up this week to check mail (in Wifi hotspots), I get the warning that data roaming is off, etc etc. FWIW, I've got the latest version of iOS installed (4.2.1). So, how has my phone managed to run up this bill for data usage that I'm sure it shouldn't have been able to?
