If the thought of a black box jutting out of the bottom of your iPhone is too much to bear, rest easy, because it looks like a dock module isn't going to be your only option. The same company that brought us the original locoGPS is back at it again, this time with a wireless module that looks fit 'n trim enough to stow away neatly on a key ring. Wireless GPS modules are a dime a dozen these days, but what makes the so-called locoGPS Mobile Navigation Server so special is that it serves piping hot coordinates up via WiFI, not the usual Bluetooth, which is just fantastic considering that the iPhone's Bluetooth stack doesn't much like to talk to anything other than headsets. It even stores maps locally via an integrated microSD slot, which means you don't have to delete those Wiggles albums off the iPhone's storage after all. If all goes according to plan, we'll see the wireless locoGPS launch alongside its decidedly more wired sibling in June for €120 (about $183), nav software included.
