You know, there's something to be said about making something easy: people usually take advantage. So seems to be the case with AT&T's WiFi connections after the release of iPhone OS 3.0, which finally became useful when users could seamlessly connect to one of the thousands of AT&T hotspots around the nation rather than having to stumble through a painfully long process on iPhone OS 2.x. According to an AT&T spokesperson speaking with AppleInsider, the amount of iPhone users linking up with AT&T's WiFi network tripled in June, and overall, it saw a 41 percent increase in connections compared to the prior quarter. It comes as no surprise to hear that AT&T is working feverishly to expand said network in order to relieve strain from its house of cards-styled 3G network, and while we'd definitely prefer a bit more reliability with the latter, we'll happily accept more WiFi in the meanwhile.
