Sometimes it's very difficult to understand Google: in 2008, Google released a great iGoogle interface optimized for iPhone, but it was discontinued one year later. "We've decided to direct iPhone users to the standard mobile iGoogle page. We've found that people hit iGoogle from lots of different phones -- we want to ensure you'll all see the same version," said a Google employee in January.
The regular mobile interface is very basic and it's only able to show feeds and a small number of gadgets. The mobile iGoogle doesn't have tabs and it's optimized for WAP phones, not for today's smartphones.
Google changed its and mind and decided to release a new iGoogle version for iPhone and Android phones. "This new version is faster and easier to use. It supports tabs as well as more of your favorite gadgets, including those built by third-party developers. (...) One of our favorite new features is the in-line display of articles for feed-based gadgets. That means you can read article summaries without leaving the page. You can also rearrange gadget order or keep your favorite gadgets open for your next visit."
To see the new version, visit iGoogle.com if you have an iPhone or an Android phone and click on "Try the new Mobile iGoogle". Google doesn't let you switch to the new version, so you need to bookmark the page. If you have a different phone with a WebKit browser, try to see if this page works well: http://www.google.com/m/ig?uipref=6.
