Too bad sprint is discontinuing the Samsung Airave service within the next month or so. You should get a letter in the mail.. I have had all 3 models.. Samsung was solid, always had problems with the Airave 2.0, have been through 4 Airave 2.5s.. Once I got the 2.5 working it appeared to be just okay... sometimes phones calls sounded robotic, or a huge delay.. Sprint update the Firmware on the airave a couple of weeks ago to 5.0.1.44 or something like that, and it appears to have "killed" a bunch of Ariaves, including mine. I think it hosed the GPS sync.. they sent me another last week, and it cam up and has been most excellent since then.. voice quality has excellent.. I would say the best ever since I've been using the Airave.. Have had NO problems with my HTC one with the latest airave.
