Opera Software released a final version of its new browser for wireless handsets, known as Mini, and said it hopes to spur increased use of the mobile Internet by distributing the application free of charge. The browser was designed as a simplified version of the Norwegian software maker’s previous wireless offering, Opera Mobile Browser, which is meant to run on so-called smartphones, or sophisticated wireless devices that offer the memory to store and run such applications. Mini claims to deliver a better Web experience to more low-end devices, or any handset capable of running Java-based mobile applications, which includes many popular phones already in the hands of consumers.
