Hello
I can't comment on how things load in cellphones or there browsers. I know nothing of that software and it is highly proprietary.
This software and the links are all coded the same across all 3 our products and it is 100% XHTML compliant. It works and operates on all browsers that we know of ( IE, Mozilla, Safari and Opera ).
Now your table thing is easy. When using the sidebar to make sure it does not break out of the table cell and looks right you simply want to set Photopost width to 100% and then create in the header and footer files of Photopost the following constrainer table
<table width ="770" cellspadding="0" cellspacing="0" border="0" align="center">
<tr>
<td>
then in the footer
</td>
</tr>
</table>
