hacksugar: Putting iPod touch GPS to the test with roqyBluetooth

A few weeks ago, I wrote lovingly about GPS. For me, at least, GPS on the iPhone OS family is often more about the social features that location unlocks than about simple positioning.

It's a system hack that allows you to connect an iPod or an early model iPhone to an external GPS receiver over Bluetooth. Yesterday, I finally got a chance to put RoqyBT to the test.

Retailing for 8 Euros (about $11), roqyBluetooth is a jailbreak application sold through Cydia and the Rock Store. Its Bluetooth stack implementation hooks into the iPod's Core Location system services.

It works. I bought a simple Bluetooth GPS unit from Semsons.com for about $20. After installing roqyBluetooth and pairing it with my BT GPS, I was able to run Trailguru and track my progress through several trips as I walked and drove to various locations.
