Additional details: We've jailbroken the device and performed a tcpdump capture of the 3G packets (while the device is sitting idle). The traffic appears to be a semi-constant HTTPS connection to an Apple run server: Primary name: p02-quota.icloud.com.akadns.net Within about 20 seconds of connecting the iCloud account, the HTTPS connection is opened and the seemingly sustained data connection begins (1 kbyte/sec). Doing a MITM capture of what's actually going back and forth probably wouldn't help us at this point. It's just enough to know that it is indeed iCloud causing this data drain.
