Just updating this thread.. I see the Go's are now in stock in the Uk for £499. With a 600min airtime plan which lasts 360 days I can have a very solid off-shore solution for £1100 all in which sounds pretty darn good to me.
I do still have some questions that I'm finding hard to get answers to however so if anyone has one of these now please let me know how you're finding it.
1. How do calls works? I get that you use your iPhone
via wifi- so sort of like Skype. This makes sense for outgoing calls but what about incoming? Does the GO box alert you to an incoming call so you can connect your iPhone
to the wifi
2. In terms of email compression
it looks like the GO comes with apps that handle this. So xGate, etc wouldn't be needed as far as I can tell I just use their app to send and receive email
3. Gribs are something I'm going to need but I'm unsure how this works with iPads / iPhones. How do you get your grib into such apps I use on the iPad
for gribs which download them directly?
