the sizes I listed are unspomrecsed.  Several of the other clients use compression as well. Compression can speed up page loads and reduce cost, but it doesn't help with phones that use the Motorola MIB and Openwave browsers which have limited page buffer sizes of 20-30 KB. Uncompressed size is a better indicator of whether a page will work on browsers with limited page memory and is what the Ready.mobi and MobileOK checkers measure as well.
