ok - looks like I've got exactly the same problem with my 8502. Patched the phone and downloads via 802.11g fail, and the phone sometimes crashes, and I need to remove battery to reset, either way the Wireless manager is screwed.
Tried it about 6-7 times - same result. NextG works fine for downloading the same file (GoogleMaps).
Anyways I uninstalled the 777 SDHC driver, and the 8502 11g downloads work perfectly again.

The Memory card was working fine though - no problems there, just the 11g stuff.
