Sorry if this has been posted before but I can't seem to find anything in this forum.

I have been having an issue with my iphone 4 (O.S 4.1). I use General -> Usage to track my data usage but it seems to be inaccurate. The other day I checked and my total usage was 100+mb up to that point of time. Later on that day, I decided to just go back and check again and to my shock, it registered 4GB incoming and 4GB outgoing!!!!!!  I was shocked so I called up Digi hotline to ask and they told me that my usage was only about 14mb total to date. So i figured that there might be a mistake, so I reset the counter. I also make sure that I don't enable 3G and mobile data if not in use cos I heard a lot of cases of data leakage. While these settings were off, I tried using safari with wifi (3G turned off) and also sending sms to confirm that these actions will not have an effect on the data usage counter. True enough, there was no impact.

So things were ok for a few days. Then just now, the same thing happened again. I opened "General -> Usage" and there it was again! Data received = 4GB and Data Sent = 4GB!!

Anybody experienced this can help?? If not, where can I seek help?
