AT&T with the launch of the Infuse 4G last night at least partly reversed a longstanding policy on Android phones that had drawn criticism from those hoping to switch away from the iPhone. Review units given out at the event had the option to load apps from "unknown sources" beyond Android Market that had previously been purposefully removed on all AT&T Android hardware. It wasn't evident whether this was specific to the Infuse 4G or a broad policy, but as one of AT&T's flagship phones would be more likely to represent the carrier's overall attitude.
