The Opera browser for Java-enabled phones is now out, and available at the Opera Mini page. It's free, although you'll obviously be charged for the bandwidth to download it, and comes in two flavors: Low and High memory. The high memory version just includes more options, with a better text and image rendering system on board. One nice feature of Opera Mini: pages are optimized before being sent to your phone, which not only loads pages faster, but will cost you less when browsing because pages won't require as much data to send.
