HTC SDA (USA) / SP5m (Tornado)

The Sda has 64mb of memory with 19.94mb of storage memory and 45.06mb of program memory. The phone from t-mobile comes with 19mb of storage memory already on the phone. So, I'm not able to put any software on my device. It says I don't have any memory even though I have over 20mb of program memory available. What can I do? I have a 1gb mini-sd care where I put everything I can, but I need to put the program on the device for the icon right? T-mobile support said they don't know how to allocate the memory so I have more storage memory and less program memory, does anyone know? Please help I have a lot of programs I want on my phone for school and work but it won't allow me to until I can free up memory.
