How to monitor iphone bandwidth for app testing? I'm testing an iphone app someone has developed for me. It seems that some of the files the app downloads are too large. 

Is there an app that monitors the network to allow me how much data my app consumes?
If your developer has given you the source code you could use Instruments.app which can be used to monitor network activity.


Open the project in Xcode
Select Product->Profile from the menu
When Instruments opens select 'Activity Monitor' and then hit record
