Latex gasket / edge hell

Question

I struggled for too long with the latex table. I need a table with centered headings and body cells that contain text that can wrap around. Due to the requirement of wrapping, I use p {xxx} instead of l to indicate the width of the cells. The problem is that the contents of the cells do not remain justified, so it looks like scattered garbage. To fix this problem, I use \ flushleft for each cell. This leaves reasonable content, but puts a ton of white space above and below the contents of the cell. Is there a way to stop \ flushleft (or \ center, for that matter) in order to stop adding a plentiful amount of valid spaces?

thank

\begin{landscape}
    \centering
    % using p{xxx} here to wrap long text instead of overflowing it
    \begin{longtable}{ | p{4cm} || p{3cm} | p{3cm} | p{3cm} | p{3cm} | p{3cm} |}
        \hline
         & 
        % these are table headings.  the \center is causing a ton of whitespace as well
        \begin{center} \textbf{HTC HD2} \end{center} & 
        \begin{center} \textbf{Motorola Milestone} \end{center} & 
        \begin{center} \textbf{Nokia N900} \end{center} & 
        \begin{center} \textbf{RIM Blackberry Bold 9700} \end{center} &
        \begin{center} \textbf{Apple iPhone 3GS} \end{center} \\
        \hline
        \hline
        % using flushleft here to left-justify, but again it is causing a ton of white space above and below cell contents.
        \begin{flushleft}OS / Platform \end{flushleft}& 
        \begin{flushleft}Windows Mobile 6.5 \end{flushleft}& 
        \begin{flushleft}Google Android 2.1 \end{flushleft}& 
        \begin{flushleft}Maemo \end{flushleft}& 
        \begin{flushleft}Blackberry OS 5.0 \end{flushleft}& 
        \begin{flushleft}iPhone OS 3.1 \end{flushleft} \\           
        \hline
