I have my ipad tethered to my iphone 3g using MyWi as I see a lot of others have done. I haven't been using this much more than I would use myiphone but since I've only be using it for a couple of days I thought it would be interesting to see what it's done to mydata usage. Obviously myrouter ismy first choice but when I'm not at home the iphone steps up. I just checked my ATT bill and my usage for March is 3 times that of my previous months typicall usage. Thats threee times the monthly average burned through in 2 days of tethering. Thats huge... If the 3g version of the ipad burns through this much data it's going to overnight hit the ATT network like a bomb. I assume richer content is using more data but I'm suprised as my browsing habits haven't altered that much. Anyone else with Mywi seeing massive data increases on their ATT summary?
