I was able to plug in the APNs manually and use the new access point.

I can't say for sure if this will work, but this is what I do. I go to: settings/wireless and network/mobile networks/use package data. Disconnect use package data and wait for the 4g symbol in the notification bar to disappear, then reselect it. Press the home button and pull the notification bar down and connect the wifi and then disconnect it. That should work for you. If you are rooted, there is an app for root only that skips this directory and takes you right to it. It's called "2g-3g OnOff". Saves me tons of time. Hope this helps.I had trouble too... had to restart it, which took 30 seconds and it works fine now. Don't know how to fix it without restarting.
