[Q] how to find the app thats constantly uploading data from my phone ?

hi,

i've recently noticed that my phone is constantly uploading data at 2.5 mbps whenever i connect to a wifi network. I assumed it was syncing my photos to FB or dropbox but then i turned off the sync and it was still uploading (i use network monitor mini to monitor the data transfer)


so my question is - Is there an app that can tell me which app or service is using up all this bandwidth ? i tried using onavo and even the default data monitor but they only monitor the 3g usage.
