how to increase shldr flexibility?

[rx123]

I read in some fitness mag this month about proper shoulder flexibility. I've always had bad flexibility in the shoulders and seems i'm not even close to passing this test. The test was as follows:

put one are straight up in the air
bend it at a 90 deg angle so your fingers are touching your upper back
with your other arm, reach behind and try to touch you other fingers
it said you should be within 2 inches from touching them

Is this an accurate test? What stretches increase flexibility?

thanks
