So there's good news and bad news, and we're not even giving you the option of choosing which you'd prefer to hear first (hint: it's the good). Sprint has dropped the price of its Phone-as-Modem plan (capped at 5GB monthly) to just $15 per month. Now, the rest of the story. First off, you must own a Power Vision phone with connection capabilities to a laptop. Next -- unlike the old PAM plan which ran $49.99 / month all by itself -- this "attachable plan" requires you to have another data plan already on your account. For instance, the BlackBerry Personal Pack ($30 / month) or the Worldwide Data Plan ($70 / month). In the end, it looks as if tethering in and of itself got cheaper, but those newfound strings that are reportedly attached will likely cause some frustration.
