This question comes up all the time so I'm going to lay out the facts and stick this message permanently at the top of the page. There are currently no options for using Wi-Fi or Bluetooth with the Tungsten E. SanDisk makes a Wi-Fi SD card but there is, as yet, no Palm OS 5 driver for it. One is expected in the first quarter of 2004. You can read more about this at: www.brighthand.com/article/SanDisk_Explains_Delay_of_Wi-Fi_SD_Card?site=Palm Update: SanDisk's web page about its Wi-Fi SD card now says that a Palm OS 5 driver will be released in the second quarter of this year. palmOne sells a Bluetooth SD card but there is also no Palm OS 5 driver for it, only a Palm OS 4 one. There are no plans to write a Palm OS 5 driver, either. This comes stright from a palmOne VP I talked to. The Tungsten E can't use the Enfora Wi-Fi case because it doesn't offer a Universal Connector. I'm sorry to have to be the bearer of bad news, but that's the way it is. If wireless networking is important to you, frankly, I'd suggest taking your Tungsten E back and getting a different model. The Tungsten T2 has Bluetooth and a Universal Connector and Shopper.com shows numerous places selling it for about $330. If you have to have Wi-Fi right now, Shopper.com shows the Tungsten C selling in several places for less than $400.
