Mobile Jorge has uncovered another useful new entrant to the Java/S60 software scene, in the form of the strangely named J1CK.Tweet, a Java-based Twitter client that works flawlessly on S60 3rd and 5th Edition phones and which, from the screenshots, appears to be challenging the commercial Gravity client, with Twitpic support, multiple accounts, trending topics, and more. Well worth a look, seeing as J1CK.Tweet is (beta) freeware.
