Nokia DT-22 tripod is semi good. Price was about 20Euro and i just bought it used for 5 Euro. You can adjust the length of the legs and the locking mechanism is OK, but over time might get loose and brake down. The place you put the phone is pretty good. You can take it off from the nokia tripod and put it to any other normal tripod! Im using it with Samsung PIXON 8mp version. Its really awesome at night shots. I ofcourse use better cameras for real.
So if you plan on taking photos at night with phone this is a must. Its worth the price, if you dont use it with phone you can use it with any camera too. Quality is 8/10 for the tripod and 7/10 for the phone end where you plug your phone.
I hope this helps to decide will you buy it or not.
