Gotcha! I just didn't know if by downloading Astro to get Swype, I would be installing a task killer that would be running the background or something without me really knowing. Considering I don't open documents much or have a really big need for a file manager, the whole notion of Astro (and anything that has to do with my files and the internal aspect of the phone) kinda confuses me because it seems to do so much.
In general, I'm extra worried about messing up my phone. I think I mentioned before that this is my first smartphone (if it's not glaringly obvious by my questions) and it runs perfectly. I mean insane call quality (55dbm), really fast, no dust under the screen, no memory problems, battery life is great etc. So by downloading things I don't know how to use just worries me because if something gets messed up, I have no idea how to fix it.
