@ Griff_LI -- steady on there, I was just asking about the list that was mentioned. The section on Goldcards was a little contradictory in places. I feel I have a clearer answer from this thread.
Follow up question. When we say 'SD card', we presumably mean a micro SD, as it has to go in the phone (I know that sounds obvious, just covering all the bases).
Second follow up (assuming it's a micro SD we're talking about). Can I use the 4GB Micro SD that came with the phone? Or is the gold card something I should keep as an archive for the life of my phone? Or can I also use the card for additional storage when it's also being used as a Goldcard?
Thanks in advance, I know these are probably horrible n00b questions, but I seem to have a real technical block when it comes to cell phones.
