Apps, games. Whatever.
Some of useful apps for free that I use on the daily basis are TextNow for unlimited text, Dictionary for looking up big words, Facebook to keep in touch with friends, Stanza to read ebook on my iPod Touch, Shazam to find out the name of the musician and the name of the song. As for free game app I like cube runner and fling. Check out the review of fling that i wrote at http://www.itrix.info
