He's back, folks. Our main dude Josh Topolsky will be infiltrating America's minds directly from the set of Late Night with Jimmy Fallon this evening -- and it's been an absolutely huge few weeks in gadgets, so trust us when we say JT's well-stocked with hot new gear to show off. Tune in on your local NBC station at the times listed below, let us know how he's doing in comments, and make sure to include #joshtops in your tweets!

P.S.- In case you missed Josh and Jimmy goofing around with the iPhone 3GS in June or the Pre back in March, we've got videos after the break.
