What does this whole article basically say? I read it but I don't understand it at all. Please helpp! I got the tethering part, but I'd like to know if this whole plan includes texting. Because that's basically all I need. And I surf the web a lot. And I'd listen to music & probably watch movies or videos on it.

Also, does this apply to Blackberries? Because this article only states iPhones and iPads.
