for the last two months every night at around 2230-2300 my account is updated with the data usage for the day - for the last month this has ranged from 1-7584kb, however; at the stroke of midnight there is a second update for much larger amounts - from 5,026-287,000 meaning I've torn though my 1GB (500mb allowance and 500mb bolt-on) in three and six days respectively!
i've been advised all the usual bumph from O2; delete apps that might use a lot of data, close them down instead of running them in the background, turn of location services. But my actual usage patterns have not changed. I never did these before and never used this much data so I'm not sure it's that but have dutifully done these things to limited effect.
One super-helpful guy in-store looked into it and suggested it was an Apple glitch and that downloading the new OS would help but it hasn't unfortunately.
Actually on one day I deleted every single app in order to clear space on my phone to download the new OS and still managed to use 30,000kb!
Anyway has anyone experienced this/got any ideas how to fix it?
