First time smartphone user here so if this is a silly question, please excuse me... My DI came and I got the 2gb microsd with it but haven't used it since I ordered a 16gb card ... but it won't be here for a few more days. In the meantime, I thought I'd use the 8gb card I had in my Dare with all my MP3s on it - not really thinking too much of it ... I just wanted to get my music on the phone and thought that was the quickest, easiest way. I don't really remember much about how my DI recognized the card but I guess smartphones format the card to work with them. Now my 8gb card will only show directories for /my sounds, /my media, etc. All of my MP3s seem protected (I can't even see the files) and I suppose that's where all of the data for some of the apps that I've already downloaded are as well. My question is this: When the 16gb card gets here ... can I just insert the new card, re-copy my MP3s to a folder, and be okay - or will the apps that I've got installed fail to work properly (because some of their data is on the old card)? Would I have to reset the phone ( or uninstall all the apps ) to format the new card and re-download all the apps? I hoe that all came out right ... Anyone know the answer in laypersons terms. Heh.
