The 'trick' I use when shooting into the sun is to 'meter' off the blue sky (point the camera at the blue sky and then press the '*' button--this 'locks' the exposure), and then recompose. The camera then meters for the 'blue sky' so when you shoot into the sun you still get 'blue sky'. Alternatively, you could meter off the blue sky - see what parameters the camera choose, switch the manual and then use those same parameters. You'll have the experiment a little to get the results you want.
