Not everyone has a fully-featured browser on a high-end smartphone. Some of us have more affordable mobile phones - and for internet browsing on many phones, Opera Mini is the way to go. Especially now the 5.1 update has landed.The world’s most popular mobile phone browser (over 61 million users worldwide) it works well in limited space and with limited screen space. Or as Lars Boilesen, CEO, Opera Software says: 'The goal with Opera Mini is to make the Web available to anyone, anywhere, regardless of where they come from or the handset they have.' So far, that's an impressive 3,000 mobile phones.The latest updates builds on those foundations, including a new optimised browser skin allowing for more pages to be open at the same time, more rapid scrolling through pages, and overall improved browsing performance. According to Opera, the update is highly recommended for users of Nokia S40 feature phones with limited memory, such as the Nokia 5130 XpressMusic, Nokia 6300 and Nokia 2700 handsets, as well as small screen handsets like the Sony Ericsson K550i and Sony Ericsson W810i phones. It also helps if you are paying as you go for the data you use. Opera Mini compresses data by up to 90 per cent before sending content to the phone, resulting in faster page loading and speed, as well as translating to lower data costs.
