Ok, so here's how it goes: I came at a friends house for a party, bringing my DS, among other things. So it works, and I play for a bit before handing it over to someone else to play for a while. When he booted up Pokemon Diamond, it crashed and so I decided to take a look at it. I re-booted the DS and it said SD/TF Card Red Error. So my first instinct was to take my Micro SD card out and put it back in. After that, it gave me the same error. I tried again, and what do you know? The same thing happened! After several tries, I noticed that something was wrong. Luckily for me, there was someone else with exactly the same flash cart. So I asked if I could try put my Micro SD card into his M3 Simply, and then it didn't read either. So I decided that the SD card was the problem, so I handed it over to another guy so he could take a look at it. And for some reason, it ended up in his phone! Now why he would think of doing that is beyond me. He apparently thought that because they were roughly the same size that it could fit. So I tried to take it out, and guess what? It got jammed in there. So now I got no SD card for my M3 Simply. I'm thinking of buying a new one, seeing as there is no other clear way of getting it out of the guy's phone or trying to fix it if I get it out somehow. I found a good offer for £8.90 ($17.65) for a 4GB Micro SD card, and seeing as I don't have anything in mind of getting at the moment, I suppose I could give some money up for a new SD Card. What do you guys think I should do?
