The mobile browser field is getting more and more crowded as companies look to users of the internet on the go. In looking at proxy-based browsers where all the heavy lifting is done on the server we currently have Opera Mini leading the pack with Skyfire in public beta. Today at Mobile World Congress, the BOLT browser moved into public beta. This browser was in private beta from January 15th until now and I tried it on a couple of my phones and found it to be acceptable, but not something I would choose over Opera Mini. The browser has gone through some updates though and is now available as version .86 that is significantly improved over the initial .73 build.
