Here is an interesting story that i read at Consumerist about an unlucky Nintendo 3DS owner that every time he tries to get his defective 3DS replaced, they send him another one that has a different defect!!!

"Ray is a huge Nintendo fan. Which is why it hurts so much that every time he tries to get his defective 3DS replaced, they send him another one that has a different defect. The first 3DS had dead pixels, the second had deep scratches, and the top screen was sliding on the third. Now he's on his fourth DS, and it too has troubs. The touch screen keeps slanting to a greater and greater degree. Why, Nintendo, why have you forsaken your loyal follower?"

Just a quick update. Nintendo released a new firmware that fixes Ridge Racer 3D error.

Version 2.1.0-3U of the 3DS system firmware includes "a correction for the screen freeze symptom" found in that game.

The new update also enables automatic download of future updates when wireless internet is available.

 If you have Ridge Racer 3D , I recommend you not to update your 3Ds firmware. Nintendo will release a new firmware update later this month, to fix that bug.

Here is what Nintendo said about the Ridge Racer 3D freeze:

Accompanying the system update available on June 6, it has been confirmed that under certain circumstances when making a selection before the race starts in "Grand Prix" in "Single Play" mode of the Ridge Racer 3D game, the screen sometimes freezes. If you do not install the system update at this time, the symptom will not occur.

We apologize for any inconvenience. We will have a system update in mid-June that should take care of this matter.

In Ridge Racer 3D, pressing the B Button to return from Race Selection or Machine Selection may cause the screen to freeze. If the screen does freeze, please press and hold the Power button and turn the system off then retry. There should be no impact to the save data.

The new update is out, and bring 3DS eShop , web browser and SpotPass.

Here is how to download the firmware update:

To download the update, go to System Settings, Other Settings, Page 4 then System Update. Follow the on-screen instructions and the update should begin to download. To ensure you do not encounter any problems, make sure that the 3DS is downloading an update where the Internet connection is strong and make sure to plug it into the charger while updating.
