Q's for PDA users

[WeaponX]

sir, usually WEP lang di ba? very rarely WPA/WPA2?

IMHO, mostly yung free wi-fi hotspots wala ng WEP. Kung meron man, syempre ibibigay din sa yo yung key para ma-access. Useless di ba kung for public access naman. Yung WPA/WPA2 gamit sa corp./enterprise networks that need high security.
