After I got my Droid I started to notice apps popping up in the Market that were stock apps on my phone (YouTube, Google Search, GMail, Facebook...etc). At first I downloaded them when I saw them pop up with the thinking that the market wouldn't let me know if there was an update available for the stock apps on the phone, but if I went ahead and downloaded them then it would. That theory seems to be working for the most part but now I'm running into a problem where I get low on phone memory quite often. Normally I go through and trim out some apps that I don't really need but now its starting to get to the point where I really would like to keep most of them that I currently have. So my question is are the apps I downloaded that were already installed on the phone taking up extra space that could be valuable, and if I do delete them, will I be stuck with the same version that is installed on the phone? Sorry if this has been addressed in the past, just trying to free up some memory. Also, I do have apps 2 sd and move over everything that I possibly can.
