I live in an area where DSL, FIOS, Cable, etc etc internet options aren't available. I want to know what DSL Dry Loop is and if it's available. Also how can I use my Blackberry to tether to my computer or to a wireless router. I have places in my home where i get service and places where i don't so i'd like to have a wireless router to "blanket" my home with internet access. Is 2 gig of download a month a lot or a little, example-using a Roku to watch netflix movies every night. how quickly could i hit the 2 gig limit.
