Solved: Nokia N9 can't connect to Twitter

After I had my Nokia N9 early this month, I setup my Twitter account first — after some basic phone settings, of course. Everything worked. The application is probably not the best, but it works.
Is it problem-free app? I thought so, until I got a problem: I can’t connect to Twitter using this app. I was not sure when the problem occurred for the first time. I did played with my phone (installing apps, downloading musics, adjusting settings, and including working from the command line). When an update was available, I also upgraded.
Added later: I was not sure what caused this problem. When I signed-in for the first time, everything worked without any issues. I deleted my Twitter account from the app, and tried to add it again. I forgot when I did this for sure, before or after installing the firmware update. It  was optional, but I decided to upgrade.
2011-11-13 01-49-48At first, I was not sure about the problem. Is it my phone, or the internet connection I was using. I switched to some different connections, but it didn’t solve my problem. When I tapped the “Sign In” button, it said: “Can’t connect to Twitter”.
So, I searched for a solution. And, I got one. It’s probably something too technical, but the instruction is easy to understand. According to the forum thread, here are some steps to fix the problem — I’m using Software Version: PR1.1 (20.2011.40-2_PR_005):

  • Activate “Developer mode” by going to: Settings > Security > Developer mode. It’s OFF by default. Turn it ON.
  • After having it activated, you will find a “Terminal” app button under application menu.
  • Open it and you need to execute these commands (one command per line):
    • gconftool --recursive-unset /system/http_proxy
    • gconftool --recursive-unset /system/proxy
    • gconftool --recursive-unset /system/osso

You may close your Terminal.
Those commands will wipe your active connection settings (bluetooth and internet data). But, it’s not a problem as I can add/manage connection settings easily. Problem fixed. Great.

    1. I’m not sure whether it works for all carriers or not, but I just pull out the SIM card, and insert it again. The data connection was detected automatically.

      1. To elaborate on this – once you remove run these commands, you do lose your mobile network settings (APN) . By removing and inserting the SIM card, the mobile network APN settings do eventually come back, but you have to remember to connect to it manually the first time.

  1. I’ve just configured my new N9 handset but I’m having a problem connecting to the internet.I
    currently subscribe to the Phone First Web Plus internet plan, which I
    used with my previous phone (N900). I’ve set up the new phone with the
    same connection settings, but I cannot connect. I connect fine over
    WiFi, so this is clearly a configuration problem. Any suggestions?

  2. Thanks a lot!! Seems this solved my problem, sharing did’t work, nor skype, and there was some weird account connection problems. At least sharing through 3g seems to work now!
