Chalk this one up as a wild rumour until further substantiation but PocketPC-Live.com is reporting that the just announced Sony Ericsson XPERIA X1 could run on Windows Mobile 6.5, a pre-release to WM7. The site also reports that the XPERIA X1 will use either a Qualcomm MSM7200 or 7500 chipset. Unfortunately, there are no details as to where the site got this information.
This is the first that I hear of Windows Mobile 6.5. To date, we have seen leaks about Windows Mobile 6.1 and Microsoft is hard at work on Windows Mobile 7. Assuming this rumour is legitimate, it seems that WM6.5 could be no more than an early build of WM7. Perhaps that explains why Sony Ericsson would not show much more than the XPERIA Panels interface during the Mobile World Congress.
Let’s see if this story goes anywhere…
