I have to return my GN2 and exchange it, because the problem cannot be fixed said one of the sprint store reps. The problem that I had started on Friday, my wifi connection had very poor signal and a very slow link speed and on Saturday it finally stop working, every time that I tried to connect to my home router it said authentication error and wrong password so I even took out the password of my router to make it open and nothing still the same error with or w/o password protection and I even went to different places with wifi and nothing same thing. Everything else works fine so I'm going tomorrow to see if they have a replacement.......
