Nokia has launched a mini-site at browser.nokia.com alerting users that there might be an updated browser available for their phone. The site touts the features of the new Symbian and MeeGo browsers and Nokia's proxy based browser for recent S40 phones.
According to Nokia, Browser 7.3 for Symbian is available for all Symbian 3 and S60 5th edition phones and for selected S60 3rd edition Feature Pack 2 (FP2) phones like the N79 and N96. Supposedly you can update the browser on these phones by running the Software Update app on the phone.
I ran Software Update on my N8 which still has the old 7.2 version of the Symbian browser but no update was available. I suspect that Symbian Anna is a prerequisite for the 7.3 browser. Because my N8 is a NAM version, which Nokia seems to have forgotten exists, it's stuck for now on the old pre-Anna PR 1.2 firmware with neither Anna nor Browser 7.3.
In what most surely is a typo, the site refers to the Nokia N95 a FP2 phone and suggests that browser 7.3 is available for it. Of course, the N95 is a S60 3rd. ed. FP1 phone and as such is not eligible for the upgrade.
The MeeGo section covers the N9 browser's state of the art WebKit2 engine and support for HTML5 and CSS3. It's also the only Nokia browser that supports Geolocation. I'm hoping to eventually get an N9 review unit so that I can put, what by all accounts is the best current mobile browser though its paces.
The Nokia Browser (formerly the Ovi Browser) for S40 mobile phones looks interesting as well. Like Opera Mimi, Bolt and the UC Browser it's a proxy based browser. Web pages are pre-rendered and compressed before being sent to the thin Java ME client on the phone.
The proxy architecture cuts data traffic and page loading times by up to 90% making using the web fast, thrifty and enjoyable even on inexpensive feature phones on slow networks.
