I just bought the Sprint EVO with 4G, also got the hotspot plan. For the past 48 hours I have not been able to connect to the 4G service at all. I have talked to two techs at Sprint. They suggested I had a faulty phone. Went back to Sprint and they gave me a replacement phone. Still no 4G service. Is this what I should expect 4G service after reading all the posts about Chicago being the "example" city for 4G? Are others experiencing the same thing? Is there currently an outage and I just need to wait it out? Can anyone shed any light?
