I'm running my iPhone v3.1.3 3G and latest MyWi from Rock App, paid version. The calculations beyond 1mb is not accurate, it resets to 0 after 1.0mb.

Additionally if you are trying to use USB/BT only without enabling the hotspot it will NOT count beyond 1.0mb it resets to 0 as it always does but instead of going up from there it just stops.

Both count properly from the lock screen though.

Additionally, if you are using USB/BT to tether it says 'Internet Tethering' and then a bandwidth count which runs over the edge on the lock screen.

Can't you turn the bandwidth count off? I personally don't think it is very helpful at all!
