Wordy is a free dictionary for mobile phones based on the Barron`s GRE Wordlist. It is created using j2me and should work on all java enabled handsets (I have tested it only on Sony Ericsson k750i). It should also be helpful for actual GRE, TOEFL or GMAT preparation. All new version is out WORDY v2.0 (http://www.getjar.com/products/9269/Wordy2)
