iLounge is still accepting entries for our Quest for the Best iPhone App Contest, so if you haven’t yet entered, now’s your chance. In the contest, iLounge and Bowers & Wilkins are giving away three of B&W’s Zeppelin speaker systems to our three favorite native iPhone applications. To enter the contest, simply submit your application to our Application Gallery, which will highlight new iPhone software with individual listings and information for each application. One winner will be picked from each of three categories: Games, Business/Professional, and Just Plain Cool, with each winner receiving their own Zeppelin system plus a $100 Apple Store Gift Card. The contest runs through July 23, and only official, App Store-ready applications will be considered, with the winners being announced on July 25.
Below we’ve highlighted some of the great submissions we’ve already received.

iToony, a new app that lets users take photos, decorate them with drawings, captions and speech bubbles, and share the finished product on photo sharing sites or simply save it to the iPhone’s photo library. It will cost $4.99.
iTrans Language Matrix, a new application for translating many popular phrases from one language to another using the iPhone’s touch screen and audio and visual features. It will cost $24.99.
Briefcase, an application that allows an iPhone to wirelessly connect to any local Mac using Bonjour zero-configuration networking technology, or over the internet if the remote computer has its own IP address.
Once connected, users can browse, view, and download files, with support for Word, Excel, PDF, MPEG4, MP3, Pages, and other media and document file types. It will sell for $4.99.
Touch Tennis, a Pong-like game that uses the iPhone’s touch screen and accelerometer to allow for one- or two-person matches. Users can choose from different paddle sizes and various match lengths to increase the challenge. It will sell for $1.99.
