Any suggestions? And yes, I pulled the battery out and followed that advice too... which in my opinion, is ridiculous for a brand new phone.
I realize that it may seem like alot on a device that has 64mb.... but what was your free memory when you checked it? If it's lower that 16mb free you will likely encounter issues.
If you have not installed applications I am guessing that applications running in the background are eating your memory. Never close programs using the Red End key. Always use Menu>End (or Close)
To see what you have running in the background press ALT+Esc (If you see more running than 5 apps you have things running in the background.
