Creating Matrix from vectors specific issue.

Thanks to all who replied before
My exact problem is as follows..
I am getting vectors from my program which is of the form
v1 = {{1},{2},{3}};
v2 = {{4},{5},{6}};
BUT NOT v1 = {1,2,3} and v2 = {4,5,6}

Now if i use A = {v1,v2} and then Transpose[A] i am getting the
required matrix only in the 2nd case i.e when v1 =  {1,2,3} and
similarly v2.
However when i use the same A = {v1,v2} in the 1st case and then
Transpose[] i.e when v1 =
{{1},{2},{3}} and similarly v2, i am not getting the required matrix.
If anyone would help me with this specific point it will be helpful.

I have also seen that the dimension in case 1 is {3,1} while that in
case 2 is {3}. If there is any way to interchange the two .. that also
will suffice. i.e if i can change {{1},{2},{3}} to {1,2,3} that will
also suffice.

Please help.
