Just got my statement and been charged £4.67 presumably for going over my 500MB limit.
Looking at the mobile data usage something seems to be triggering huge amounts of usage at midnight - every night.
My iPhone 4S is set to flight mode before I go to bed every evening without fail - and most days this is well before midnight. I also disable "Mobile Data" usage every evening (have WIFI at home & my usage gets counted as 3G unless I disable this for some unexplained reason).
So I have absolutely no idea what this could be?
Below is just a sample as I sorted this to show the £4.67 charge but it seems to be every day.
Sat 28 Jul 00:00 Mobile internet 19.316MB 0.000 0.000
Sun 15 Jul 00:00 Mobile internet 19.117MB 0.000 0.000
Wed 25 Jul 00:00 Mobile internet 17.907MB 0.000 0.000
Fri 20 Jul 00:00 Mobile internet 17.855MB 0.000 0.000
Thu 2 Aug 00:00 Mobile internet 14.497MB 4.167 4.167
Does anyone have any idea what might be causing this?
The only large amounts of data I download are at around 8am each day when I download some newsfeeds via WIFI - with Mobile Data turned off.

The answer is the same as in your earlier post:
Unless you have a fault with your phone it is technically not possible for you to be using any of your data allowance with airplane mode on and Mobile data off. Where are you seeing the 'huge chunks' racking up?
All networks bill data alowance as an accumulative figure, to bill every single KB as and when it happens would be a logistical nightmare. If you are convinced that what you are saying is happening a visit to an Apple store for them to run a diagnostic test on the phone is your best bet.

This usage will be for usage during the day but billed as one lump sum and added at midnight.
Surely though you do use the phone during the day away from wifi?
Not sure why the phone is prioritising 3g over availiable Wifi connection, it really shouldnt.

If you take a look at the official Apple help boards you will see that thousands of people worldwide have posted with the same complaint about unexpected data charges.
In the end it remains a fact that it is the design of the phone that causes the problem and not the networks.If at work you connect to a busy wifi network and your signal is interupted for a split second the phone will revert to mobile data and it will stay there even if the wifi signal returns until whatever it was doing on mobile data either finishes or is terminated by you.
Also as already pointed out, you may be connected to a wifi network but unless the phone is connected to a power source as soon as the phone goes into sleep mode so does the phone's wifi connection and any data used comes from your mobile data allowance. So if an app tries to do something it will do so using mobile data.
