Samsung's burly new smartphone champion, the Galaxy S III, has yet to launch in the USA, but a couple of neat discounts are already on offer for its AT&T variant. Amazon Wireless and Target are both offering the Android 4.0 handset for $149.99 when you extend your AT&T contract in purchasing the GS III. As you might suspect, we're talking about the cheaper 16GB version here, and you won't be getting the 48GB of extra Dropbox storage that European users of this phone enjoy, but those things are true whoever you buy the AT&T version from. The usual provisos should be heeded here: check Amazon and Target's terms, so you know exactly what you're committing to before you do, and keep in mind that the phone is listed as backordered for now, meaning you might not get it on the first day of availability.
