I just "upgraded" to the Tour 9630 and have downloaded a few apps that I have had in the past and some similar ones to others I could no longer get. Its very hard for me to try something new and this is why. After I was done with a few I wanted, I had about 81mg left, well over the next 2 days I "lost" mg's until I was down to 13mg!!! I was amazed, I am not by any stretch a techie person and have heard of memory leaks and thought that's what it was, but read about it and realized that was another issue I must watch out for. I did remove one app I had downloaded last (although it was from a trusted developer) and all my memory came back. But I noticed its been going up and down somewhat. This phone is brand new and I paid a lot of money for it!! I'm hoping someone can help me out with this. I'd really appreciate any help at all. Thank you
