    Hi all,

    I have had iPhone since the 1st Gen, and now own an iPhone 4. Anyway, i have never really been an intensive 3G (or GPRS) data user. I had my 3Gs for 18 months and only used 3GB downloaded.

    Today i had a text from my provider (Tesco UK) saying "Tesco Mobile: Your unlimited data is subject to fair use. Please note you're nearly at the limit & will be charged £4/MB if you exceed it".

    Now, I was confused as I am on wifi at home, 3G at work and don't browse or download on 3G. I checked my usage ad it is at 5.4GB!! That's since 1st of December. Last time I looked a couple of weeks back I was on 2 GB ish.

    Luckily tesco let you downland your raw usage data, which shows me how much per minute I am using. I have put it in excel and grouped by day. I'm usually using around 10mb a day, my highest was around 400mb (i was streaming radio all day). But on the 15th it jumped to 2000mb!!!!! It looks like i have been using loads daily ever since then.

    I do not know what is doing this? I do not have any data intensive apps running. I do have gmail on exchange and google contacts on exchange as well as my work email and calendar on exchange. Could these be causing it?

    Thanks in advance

    They could, but most likely, it's an app. You can download a free app called Netstat from the app store that can help you find your problem.
