Gadget Gal's daily deals: Free Twitter iPhone app, 5th Gen 30 GB iPod, Griffin Technology and Skullcandy iPod speakers

Fifth generation 30 GB iPods, iPod speakers, and a free iPhone app. Here are your deals for Monday, March 30, straight from the Gadget Gal:

1. If you still don't have an iPod because they were just too expensive before, today is your lucky day. Woot is selling refurbished 5th generation 30 GB iPods in white or black, for only $99.99. Granted, this is a refurbished iPod, but a regular-priced version would cost you up to $349.99, and this is the lowest price I've seen for a refurbished model. The video iPod is only on sale while supplies last, or until the end of the day.

2. Head on over to Sellout.Woot to get a speaker system for that new iPod. The Griffin Technology 1200-ITSPKR Black Amplifi 2.1 Speaker System for iPod is just $39.99 today. With a list price of $179.99, you're saving quite a chunk off of the original price. The deal is only good while supplies last, or until the end of the day, but if you get to the deal too late, check out Buy.com where the Amplifi is on sale for $49.99.

4. Like cheap? How about free? Today only, get the Retweet App for the iPhone for free. The app, which normally cost 99 cents, acts

as a "retweet aggregator" for Twitter users to find the most retweeted topics on Twitter. For those of you who are unfamiliar with the term "retweet" it refers to when a Twitter user likes what another user said, and reposts the other person's writing while attributing that person. This app makes it easy to retweet and find out what other people are talking about.
