When I purchased my Blackberry a couple of years or so ago it was made clear when choosing tariffs that I was getting everything I needed to fully exploit a Blackberry. In effect I was being given a choice of basic tariffs (which didn't include data then) and a choice of size of Blackberry bolt-on to go with them (the size just affecting the data allowance for anything that wasn't routed through BIS). It was presented slightly differently so rather than saying it was an e.g. O2 50 @ £10.50 + Basics Bolt-On @ £3.00 it was presented as something like a Blackberry Basics 50 @ 13.50.
Now when I look at the tariffs for the Curve 9320, which still requires BIS, things are a little more vague as the tariffs include data allowances now. So when I see e.g. an £11 tariff with a 100Mb data allowance am I basically getting a tariff with BIS already included and no need for a bolt-on?
