Have you tried flashing another Rom and trying #3424# again? I've tried multiple ESPT.apk files and still nothing. I dial the code and nothing comes up at all. I rooted my phone (finally) in order to fix this, but when I try to use EPST nothing happens.

In the past I've fixed this by resetting my data profile by dialing #DATA# using EPST. Since then, I've been periodically getting an error, a data call failure.
#QPST 2.15 UPDATE#
Yesterday I attempted to do a profile update and it failed. Trying to get rid of an error code and EPST isn't working correctly. Question: How do you change your MAC Address? It'll scan, but then it will display disconnected. I did a tour of SF earlier haight, missions, union square, and still no 4g. All my mac address' are correct, including the RSA keys. The ROM doesnt necessarily constitute higher transfer ratesÄid you have any luck? I'm kind of in the same boat as you. Not in SF but am getting 6 mbps with that Rom in Charlotte. then run the RSA tests and MAC tests and then update to semi-new ( I went with slightly older WiMAX, radio etc just to be safe. I also backed up my RSA keys, I would do that too when you root or directly after you root.

In the end, Im now on Myn and Ive had 4g since yesterday ( first day on Myn ). I then did a deroot ( because I had flasehd over fresh and no 4g still ) and then rerooted ( funny thing is it changed my hboot from 2.02 to 2.10 ) so I had to alter a few steps. I was paranoid that I funked my rSAs I kept doing RSA and MAC checks and everything worked out. I rooted my evo and went from sprint lovers ( 4g ) to fresh ( no 4g ). Now Im not 100% sure of this but I did have issues with fresh and 4g. I'm wondering if anyone else is having this problem. Issue with 4G on Fresh 3.5.0.1? 4G just went live today in San Francisco, but I can't connect.
