used 30mb? A little confused, just wondered if anyone else knew anything about 3g watchdog as an app to keep an eye on your data usage. As I only have a 500MB allowance a month i was quite surprised i managed to use 30MB in the space of a few hours according to an app called Stats, but then on 3g watchdog I've apparently used 0%? I thought I've been using wifi as I have been at home. Any help would be appreciated
