The last we heard from a Microsoft source was that you would need to buy a new Windows Mobile device to get the Internet Explorer Mobile 6 web browser. WMExperts posted on the rumored Sprint Diamond ROM update that shows MSIE 6 in the list of new/different features. If the Sprint Touch Diamond can support IE Mobile 6 then there are a host of even more powerful devices (Touch Pro, XPERIA X1, etc.) that should be able to support it too with an update.
IE Mobile 6 was announced last year with Windows Mobile 6.1, but has not yet been released. It is supposed to drastically improve the browsing experience, although I imagine it still can't compete with Opera Mobile. However, there are times when IE is needed to access certain sites and I personally look forward to trying IE Mobile 6 on my devices.
So Microsoft, what is the deal with getting IE Mobile 6 on existing hardware? Will you really require people to buy new devices just to get a bit better web browser that should have been included with WM 6.1?
