I have a Zaurus SL-C860. I've been using an SD card for months, and taking it out occassionally to back it up using a card reader; no problems. Just now I took it out, and now when I try to put it back in, it goes in all the way, but it doesnt click into place, and so it pops back out (part way). So I can't get it to physically be "seated" properly. Does anyone know of a way to fix this, or do I have to send the unit back to Dynamism (where I purchased it)?
