With that you free long distance US/canada, no air time on your cell phone and free sms all those feature completly integrated in you N900!!!

I will probably make a explanation thread for it. Just when I have a bit of time. Basically to setup GV you need a
-US phone number
-setting it up from US
-free incoming call from your Canadian cell phone company

You can do that all from Canada

-US phone number you buy a magicjack for 20$ USA number you set it up to forward call to your cell
-You set up GV with a public proxy or IP hiding software so Google think you are in US
-When you set up GV you give you US number (magicjack)

So by doing that GV is set up to work for Canada
Then you put the one ring software from extra devil you can read the one ring thread to learn it

Then when you want to make a call you select as call type GV then One ring is going to send by data the number you want to call, GV will call your magic jack number and the number you want to call. Your magic jack is forworded to your cell so your cell is going to ring and when you answer you will have on the phone the person you wanted to call, so that whay you don't pay for call because it is incoming and there is no long distance fees for USA/Can because of GV and magic jack
