Sharp Mobilon 4600...Pocket Excel Issue

[rlnye]

I have 4 Mobilon 4600's to which I downloaded an Excel file from my PC...the problem is, Pocket Excel does not support cell protection like Excel. Does anyone know of a download that would allow Pocket Excel to protect cells? If not what type of OS would have to be installed to give me cell protection?

Thanks before hand for any help.
