Why does my cell phone, already turned on occasionally pop up a screen that states "inserting ml", which is the name of my memory card? It always happens randomly and I'm not quite sure why and would like to know what wireless technology would/could cause that to happen at intervals. I did previously have this memory card in a blackberry device and my address book.phone list is stored on it.

Maybe your new phone is getting low on memory so it is saying to enter the memory stick for more.

(I really have no idea but that's the first thing I thought off)

Try reinserting the card.
