I have a memory card from my cell phone for about two years now. I have two memory card one is more space than other, I think I have a 4gb and 8gb. I think I have the 4GB on my virgin mobile cell phone and the 8GB in my purse still in the package came in the small plastic sleeve with tape on it or something. I didn't open. If I had to put in the memory slot in my virgin mobile cell phone will my virgin mobile cell phone be damage or the memory card will get damage because I am scare to out a never been use memory card in my virgin mobile cell phone before it to late.

Memory cards are very resilient to poor handling.
All told you'll be fine.
