I'm not sure exactly when or how this happened, but one day a whole bunch of the apps that came on my phone just "disappeared". I have located them on my phone if I got to manage apps and then all, and I was able to add one of them back. Now I'm trying to get the calculator back, and I can't - it does nothing..well, I can clear all data, but I'm not sure I should do that, but I guess it doesn't matter since I can't use it anyway. I'm really wondering why this happened, and for the apps I do want - how can I get them back, or would I be better off just downloading new ones? Some of them I never used, so that's not a problem, but a calculator does come in handy, and the one I was able to get back was the alarm app. The only other thing I noticed around this time was I did download to free "live" wallpapers from the market, but not sure that had anything to do with any of this. Thanks for any help anyone can give me with this.
