Phone has arrived and after a couple of calls the USB modem and BB service are ordered - modem should arrive Tuesday.
I decided not to wait as 3 allow you to use the BB service for 3 days and if the coverage isn't as good as you expected then you can return it FoC, which is quite decent.
The existing customers discount only works on the webpage after a couple of months of you being a customer so you have to call them.
So the deal is £15/month for a K660i with 300 minutes talk/texts, 300 free minutes to 3 numbers (which includes video calls I think), free Messenger Live (all traffic free), free Skype (all mobile<->Skype free) and probably a few other add-ons that I haven't noticed yet.
Then I added 7GB/month data to that for an additional £12.50 a month making a total of £27.50/month.
I reckon if you upped the data limits to 10GB and dropped the total cost to £25/month you would have a product which sold
very well, even in the current chilly financial climate.
I'll report back on data speeds etc. I know there will be a proxy somewhere but I don't care as I'll just VPN right past it
