I'm looking to swap out the existing 2 GB card for something larger. My plan was to connect my phone to my laptop via USB and copy all the files to a temp folder on the laptop. Then copy those files to the new card(using SD adapter in the SD reader) and then swap out the cards in the phone. Is it that simple? Do I need to format the new card before copying the files? Now that I'm rooted does that have any affect on this?
