BigBoss Edit: Excellent post Ranova. Added as rule #16 to why jailbreak.

Here’s another reason to jailbreak your iPhone 3G. Today, xWaves released the highly anticipated update to their GPS app for the iPhone: xGPS. xGPS features full turn-by-turn guidance through the clever use of Google Maps. It also features full voice directions (TTS – text-to-speech) that try to pronounce the upcoming turn in full detail (direction, street name, etc), a feature a lot of standalone GPS’s do not have. It does a pretty good job at pronouncing street names. A female voice (found in most GPS units) would sound a lot better than a robotic voice, but it is still decent.
