It's been well documented that AT&T's 4G phones aren't just slow—their upload speeds are often slower than its 3G network. So what happened to that extra G? Turns out it's not the network itself that's borked; it's the phones. AT&T has intentionally crippled the Motorola Atrix and HTC Inspire—the carrier's only fourth-gen network phones—by actively disabling the handsets' HSUPA capability. Gross. But there may be sweet relief coming soon.
