Introduction: Nokia 3230 Memory Card Adapter
I found that there was a lot of space inside my phone to carry the memorycard adapter.
Step 1: Cut the Piece:
In my case from a credit card. Verify that the piece fits in the space and the cover can be closed.
Step 2: Use It:
The plastic piece reduce the noise from the memorycard adapter. So you carry everywhere your adapter, everytime that you will like to share files you use it with the memory card. Better than bluetotth for large files.
