Nokia 7705 Twist Phone, Black

i got this fone for chrismas. i havent had it long but it already gets on my nerves.! battery life sucks.! doesnt take that great of pics. n if u text alot like i do dont qet it. the touch pad on it is slow to respond and it often freezes n shuts off.
I got this phone for Christmas of ‘09.
The phone is everything I’d want from a phone and more.
It’s small, unique, and relatively easy to use.
However, problems soon arose just after a few weeks of using it.
PROS:
-Easy to use QWERTY keyboard.
-Interesting light-up ring
-Interesting “habitat” mode
-Unique design; this phone never fails getting attention from peers
-Small, compact shape makes it easy to slip into a pocket
-Excellent call quality
-GPS is the bomb
CONS
-Unique “swivel” joint broke after just 2 months. The screen and keyboard completely separated into 2 pieces. However, under the warranty I was able to get another. So far I’ve had my new phone for a month and a half without it loosening like the first one did.
-When “habitat” mode was activated, it froze the screen when I received texts or calls.
-Camera sucks. Flash sucks.
-Menu is a bit confusing/disorganized
-Talking on the phone is a little awkward
I’d recommend this phone to someone who likes to text, but who doesn’t do it too often. The constant open/close motion of the phone wears on the joint of the phone, making it easy for it to break. That’s why my first phone broke. I really do like this design of the phone. It’s really sleek and innovative, but I can see room for improvement.
I am 10 years old and got this phone for x-mas. It is light, portable and small. It has a built in mirror,and a qwerty key board.You can even put a video that YOU take as your home screen, though I find it annoying.
GREAT PHONE
