The product page says to modify Adafruit_SPITFT.cpp but this is likely referenced from an older version of the library.
It can be set with the init call, see setup() in the call to tft.init
tft.init(240, 240, SPI_MODE3);
The product page also says connect to 5v but it appears to run fine from 3.3v.
