Speak like a native with Rambler
Here's a nice piece of software for the iPod-wielding globe trekker. Rambler by CyraKnow is an audio phrase book for your iPod that features 900 common phrases across four languages (Italian, French, Spanish and German). Phrases are sorted by category for quick searches. The benefit of this vs. a paper phrase book is that you don't have to worry about getting the pronunciation right, but for those who like a hard copy, a PDF of all foreign words and phrases is included.
You can purchase one language for $12.95US, or all four languages for $34.95US.
