I have an EVO running the latest stock everything from HTC and Sprint (December 15th update.) Clearwire just launched a tower in my area and I'm trying to try 4G for the first time. However, my phone will not connect. I'm literally sitting here with a friend who has 4G on and it is working on theirs. Latest PRI, latest PRL, everything. I even did a wipe. Any help is appreciated.
