Hi Vaughn, most applications will insist on installing on to the internal memory. If you were rooted, you would an app called 'Link2SD' to move currently installed (and future download) apps to the 16GB SD card. There is a tutorial here no how you can set the default install location to SD card without rooting your phone but it is quite advance and you may not be able to follow it. The easiest way out of this is to get rooted and then use the above mentioned application to free up internal memory.
