I recently published the list of Windows Mobile 6.1 upgrades available for Windows Mobile devices however it’s an every increasing list!
Keeping track of them is quite difficult!
The easiest way to find all the available upgrades is actually to take advantage of the tagging I use. I basically tag every article with the Upgrade tag. So if you want to find all the 6.1 upgrades then use this URL!
