I am able to access the web through my Motorola T730 phone, with Verizon. They are selling the Mobile Office kit for $65 to $70, and I'm wondering if I can get a cable/kit elsewhere, for less. (I've looked on ebay, and I just might get the actual kit, we'll see.) Will it work (for both a desktop and a laptop) with just a cable? I've seen some "universal" cables for sale. Do I need software? Will doing without it slow down speeds? Any info would be appreciated, thanks.
