This phone is the strongest and only Blackberry Phone I have ever used in my life. It was the first blackberry phone I bought and it has been in my possession for over 2 years now. It is not one of the new and sleek blackberry phones but it is strong, nice and does not develop plenty faults. Infact, the only problem I have had with this phone is the trackball which I have changed a couple of times but apart from that, it is durable. It is not the best phone to consider if you are a gamer or someone who likes to take quality photographs. Battery Life The battery it came with lasted for a year before it got weak and I had to change. Display/Screen Quality The screen is ok, but not the best, Call Quality Excellent quality. You are able to hear your caller clearly and loud. Adjustable call volume too. Ease of Use It is easy to use. There are no relevant difficulties in learning to use the phone. Durability This phone is durable. I cannot count how many times it has fallen off my hand and it is still working fine. Design Nice design. Not sleek or that trendy.
