Filed under: WirelessEasy come, easy go: looks like that free WiFi for iPhone users could already turned off, as users are now reporting login screens instead of the free web access they so quickly came to expect. The only question now is whether the whole free iPhone WiFi was flipped on early and quickly turned off to be officially announced at a later time, or AT&T changed its mind about the whole thing. Guess we'll soon see.[Via Gear Diary]
