I am trying MyWi on my iPhone 3G using the free 10 day trial period. It seems to work simply and perfectly. I was able to connect my iMac to the iPhone running MyWi just as easily as I could connect it to my regular home wi-fi.

I was thinking of purchasing it and using it with an iPad wi-fi instead of getting the iPad 3G. Especially since here in Japan SoftBank is only going to sell SIM-locked iPad 3Gs!

Anyway, my question is, do the cell providers (AT&T, SoftBank, etc.) notice the increased 3G usage (or *type* of packets) when using MyWi tethering and try to lock you out or limit use?

Thanks,
