Hi can someone recommend a data usage app for my phone. I only really need it to monitor my 3g internet usage not Wi-Fi. I also want to be able to enable/disable the app when I want as I don't need it eating up system resources or battery life. I would prefer the app to be free but if I have to pay for it, I would like to buy from a UK seller so that my bank doesn't charge me any ridiculous card fees.
Thanks
Thanks
