Very new to droid, coming from Blackberry. I want to get an SMS app, but the Permissions that apps like Handcent and GoSMS say things like 'modify/delete SD card' and other things. Has anyone had this happen, lost pics or music stored on their card, possibly due to some app that's on the ph one? I had one guy in a VZ store tell me that they can possibly store something on your SD card, but can't delete it. I am just afraid of losing some things on my SD card or acquiring used minutes because an app has made phone calls I am unaware of. Is there any reason to be concerned, it seems many people use these apps. Do Anti-virus apps prevent this? My apologies, if this is unnecessarily long.
