i don't understand whats going on, but my phone has burned through 350MB in past hour or so. I checked my data earlier and saw i had 300MB left. about an hour later, i got sms that it was depleted.

I was very puzzled, but i then loaded another 50MB. After a short while, i got SMS that i have 15MB left. i then switched of data usage on every single app, and reset the stats. I left the main "use cellular data" on, but on an application level, switched everything off.

after a few minutes, i got sms to say that my bundle is kaput! so even though every app is prevented from using cellular data, something has wiped out the 15Mb i had left.

please help me understand what on earth is going on
