Ever since I read that there was a software update available for the Infuse 4G, I tried to get it. Every time I try, I'd turn my phone off, pull the battery out, and then put everything back together and turn it on again. Then I'd go over to the applications settings and force stop and clear data for the Device Management. After that I'd turn off my Wi-fi (regardless of whether I was connected or not) and let my data connection take over. Then I would prompt the phone to check for updates. It would display the blue and red arrows and say "Connecting to DM Server." But every time I do so, it always fails, showing the "Connection failed. Unable to communicate with the AT&T servers." It doesn't seem to matter if my signal is at a good 4 or 5 bars. It always fails. What does a person have to do to get this software update? How do you do it? Please help!
