So have had my Evo since end of june using my hotspot 2 power up my laptops and ps3 no problems got 4g and hotspot going at the same time than I download 2.2 and every time i power up the hotspot the 4g drops out. I call sprint and dude tells me i was one of the lucky ones that got my hotspot for free?? for the first month but now its gonna be 29.95 if i wanna use the hotspot?? hello thats why i bought the fn thing?? He said he would give me one more month for no charge but thats his final offer!! I decline and ask him to give me the president so he can tell me why sprint is sticking it 2 me once again! Does the 2.2 software allow them to turn the hotspot one and off again at will? Until I figure this all out im leaving my other evo on 2.1. Help anyone!
