I am a new bb owner/user I love the bb and before my 30days ends I want to insure my device is in the best condition for the next 2 yrs. Is it common for the keys to flex somewhat, I notice when I was using the space key the center row is flexing.
Some phones flex a bit, some do not. If you look ate the keyboard here
of a Curve being dismantled.
You will see how the keyboard is made and fitted. You will also see that the part you touch is 'just a piece of plastic'. The 'contacts' are located on the main board below the plastic part.
It just depends on the individual phone as to how they behave.
My advise (free and worth every cent): Take it back to the store and ask to see another BlackBerry (or maybe 2 or 3 ). If, after comparing the different units, you are unhappy with the behaviour of yours, demand a replacement from the store and do not take 'No' for an answer.
