If you have a problem with your Nokia 5800 phone and have put the SD card into the SIM card slot, this means you now are not able to remove it.
The easiest way to get the card out is by using a paper clip or very slim piece of firm but flexible wire.
Follow the first 2 instructions in the manual for removing the Sim card:-
1. Open the SIM cover
2. Take the Back cover off the phone
3. Bend a paper clip in a curve so it fits in the gap where you would put the stylus pen to remove the SIM card
4. If you now push it gently towards the side of the phone where the SIM pops out, it pushes the SD card out so you can remove it
