Where can I check how much Internet bandwidth did my HTC Desire use? A newb question, as I just received my wife's HTC Desire: Where can I check how much bandwidth it uses (or used during certain time period)? Her contract only includes 500MB a month, so she needs to be able to monitor this.
Mentioned 3G Watchdog probably is the best choice. Alternatively, you might want to take a look at...


NetCounter
Traffic Counter Extended
Mobile Counter
Net Traffic Counter


...which also cover your needs. Might be you like one of them more :)

Talking about more, I obviously missed...


Traffic Monitor
Traffic Monitor (same name -- other app; this one goes as deep as on per-app stats)
