Product Description:
Another great invention from SanDisk, the microSD is about a quarter of the size of an SD card and is the newest standard of SD flash memory specifically designed for use with ultra-small mobile phones and other devices. Like the miniSD, the microSD/TransFlash is ideal for use in storing media-rich files such as music, videos, and photographs in compatible mobile phones.

Well I bought a 1 gig memory card for my cell phone so I could put some ringtones and whatnot. I have put on a bunch a ringtones and it has worked very well for me. It's nice to have a memory card cause the phone has like no memory at all so it was a great buy. I would recommend it to anyone.
