These are the exact same drivers as for the Zire 71 in the mini CD for the Sandisk SD Wi-Fi card (SDWSDB-000-A10M). Not sure if they will work for the TE or T3. Why not just use the PalmOne SD Wi-Fi card (P10952U) which works on the T3, T5, Zire 72 (and even the Treo 650 via an unofficial hacked driver floating on the net). No luck on the TE though.
TE users can get Wi-Fi via Enfora's Wireless portfolio.
