Didn't notice any previous post on this (unless I missed it, in which case, sorry!)... just wondering if anyone else has noticed this: since jailbreaking my iphone 4 w/ comex's break, I've noticed that there's no data reported under the Usage section for Time since last full charge... had the phone fully charged yesterday, and it was keeping track of my usage and standby times, but then the numbers disappeared overnight...battery at 83%. Re-started phone, but still just says that usage data will be reported after the phone is fully charged. Weird.
