I am wondering if anyone else is seeing this problem too (and/or if you've found a solution).
Whenever I try to download a ZIP file over the air using PIE, I end up with a corrupted file (that won't open in Resco Explorer or Mobile WinRAR).
If I download the same file from my PC and move it to the Treo 750 then I can open it all-right.

BTW, when I download CAB files or EXE they work just fine.

Any idea?
