I've slightly confused (I pulled the tab out, what do you expect?). Droid Xs have 8gb of internal storage and 16gb (at the time of purchase) of external storage on the micro SD card. I've managed to stuff that external with MP3 but realize I have more memory internal but can't figure out how to address it. If it's for apps only then I'm further confused because I thought the Droid X only has 700+Mb for app storage, leaving the remaining 7gb for something. What is that something and how can I use it? Maybe the 700+Mb limit was just a rumor and we have the whole stinking thing for apps.
