microSD card insertion

Expandable Memory... Why doesn't the iPhone have expandable memory? We don't know but we wanted it, so we added a microSD card slot to our Xspander. Now you have unlimited expansion of your iPhone memory, up to 64GB (largest microSD card we are aware of) at a time. Transfer any Apple supported file (movies, videos, pictures, spreadsheets, etc.) from your iPhone to the Xspander microSD card or from anywhere else to the microSD card and then to your iPhone and the app is very easy to use.
