I'm having trouble find the truth answer to see if Blackberry Tour does have WiFi or not. I found some online article, check out link:
"Sprint did not set a date for when its smartphone suppliers have to include Wi-Fi, but an executive indicated that the carrier is planning to release a version of the Tour with Wi-Fi in 2010".
"However, Sprint is hoping to right this wrong by releasing a Wi-Fi-enabled BlackBerry Tour next year and said it will require all of its future smartphones to have Wi-Fi".
