Hi All,
Recently jailbreaked my Factory Unlocked iPhone 4.

All went fine. But started to experience battery drain.

I am using a "Pay as you go" sim card. So I had 200MB of 3G data limit on my card.

I keep my phone aside for a few minutes and to my horror I see that I have lost all the 200MB...

I understand that there mite be some app using my data.

Please help me to find out which app is using up all my data?

Many Thanks
