multiple problems with blackberry curve

[bookbug]

I am having multiple problems with my curve. It is displaying an hourglass every time I do anything. It can't seem to keep up. Also, I can't get my BB Maps to find my location. When I go in to the Find my Location icon it doesn't show anything but enter address. My help says that there should be an option called "where i am at" but there is no option for that. I bought this phone for the GPS and just can't get it to do anything. So frustrated in general. Can anyone help? I did purchase this phone used as a replacement phone because I am not due for an upgrade till August.

Which Curve do you have? The spinning hourglass usually indicates not enough internal memory available, and it's also commonly seen on older models with slower processors.
