Ok, I'm going to Canada tomorrow and will be the first time with something else than a Blackberry... So I downloaded "Network Monitor", disabled WiFi and used Task Killer to kill everything except "E-mail" and "gmail". When I woke up this morning, I sunk gmail (there 1 e-mail) because my gmail doesn't auto-sync anymore. Opened up the Network Monitor to find out 4.41MB up and 5.06MB down, total of 9.47MB (in 9 hours). Now, this is 20$ right there. The task running this morning : Alarm Clock Voice Dialer Gmail Settings Messaging Network Monitor Advanced Task Killer I'll try to find a per application byte counting app... I think I've seen 1 for .50 UK. Anybody has observed the same problem? Maybe my gmail sync problem is using all that bandwidth. I used to spend weeks in Canada and it would use only about 1-2MB (just e-mail).
