When I was out today, I opened safari only to get a message that I had run out of data and need to top up (Three UK). The last time I checked a week ago, I had 1.5gb left out of my 3 gb allowance. So, I checked my usage and was shocked to see that I had used 9.5 gb of data! My limit is 3 gb so that can't be accurate and, yes, I did reset the statistics when I topped up last time. I'm thinking about what I've done over the past week: browsing with wifi youtube with wifi email over 3g safari general browsing over 3g I can't think of anything else. What's going on? Even if the ipad usage stats are wrong, I don't know how I could have used the remaining 1.5gb in just a week. I usually use less than 1gb per month, often not more than 800mb or so. Any thoughts?
