What do you do after you've bought the most powerful smartphone to yet grace the Android universe? Some timid folks would urge you to just enjoy it, but if you're like us, you'll probably want to know just how high that dual-core Exynos 4210 birdie could fly. The processor inside the Galaxy S II started off life at 1GHz, then got sped up by Samsung to 1.2GHz just before release, and has now been taken all the way to 1.5GHz thanks to coolbho3000 over on the xda-developers forum. He's been nice enough to provide the source code and instructions necessary to reproduce this stable overclock on your Galaxy S II, but don't rush off just yet -- there's video of the GSII romping through Quadrant and Linpack after the break.
Pentax's Optio WG-1 GPS point-and-shoot satisfied geotaggers out of the box, but owners of its K-5, K-r and 645D DSLRs have had to make do with third-party taggers like the PhotoTrackr or Eye-Fi. The new hotshoe-mounted O-GPS1 module fixes that oversight by recording latitude, longitude, altitude, Coordinated Universal Time and shooting angle. Everyday snappers might find an extra hotshoe attachment cumbersome, but astro-photography enthusiasts could well be enticed by the device's interesting "ASTROTRACER" function. This helps you take clearer photos of celestial bodies by using the in-built sensors to calculate a star's movement and then employing the camera's shake reduction system to compensate. Sounds clever, but be advised: this module is only for Pentax DSLRs -- and only for very specific models at that. You'll get full functionality with the K-5 and K-r cameras, and geotagging (no ASTROTRACER) with the 645D. Oh, and you'll need to make sure yo
