The opera mini team were earlier initiators of mobile web browsing.I have been using this browser since I was a kid on my phone to surf websites.
Really it consumes lesser data than other web browsers.Page compression via images is probably the most helpful feature in opera mini.One thing is quite experiencable that it doesn’t have much reliable downloader.
It could be just used to browse and just download smaller mp3 in it.Another cool feature is offline saving of web sites which is very much cool.
