Sprint was serious when they said they would still be shipping out pre-orders of the 16GB versions of the Galaxy S III on time. Even though there's some sort of delay in the chain, users in the Sprint GSIII forums are getting their shipping notifications, much like RawisTheGameHhH's who you see above.
The timing is perfect, you can read both our Sprint GSIII review as well as Alex's primer on the new Touchwiz while you're waiting and refreshing the UPS tracking number. Afterwards, be sure to dive in the forums feet first -- half the fun of having a new Android phone is finding ways to fiddle around with it, and there's some pros in there who think outside the box. Now hurry UPS trucks!
