iOS5 using excessive cell data?

[OsloBergen]

Less than two weeks into the billing cycle and I was notified today that I've reached 253 Mb of my 200 Mb plan. I checked At&t and one of my nightly data dumps was 172 Mb. Another, more recent, night was around 73 Mb. This is a great way to get people to upgrade their data plan.

Just wanted to add my voice here.

My iPhone 3GS is eating data recently, a huge amount. It looks like it is using data even when connected to Wifi. This is my data use yesterday, I was at home on Wifi the entire day.

The timing of the large chunks of data use is the same time I use the app TuneIn Radio. I have noticed in the last 2 months the monitor built into TuneIn Radio shows cell data at 2GB. So I am monitoring this app now to see if it is pulling data instead of Wifi.

I have iCloud turned off, so it isn't eating data. I am unsure what else might be using it. I will monitor it further over the next month, as I have gone over my 1GB limit this month.
