Any Zaurus guru's still around, need words of wisdom (or kick in the bu_t) on unzipping a v 3.13 ROM upgrade so I can flash it. WinZip keeps telling me the file is too big and instead offers to open it with WordPad, rather than extract it (no bueno). Trying to upgrade my old (2002) SL-5500 with ROM v 2.12 and 2.4.6 Kernel. TIA Lou
