Alright, so it's no secret that the upgrade path to Windows Mobile 6.5
is pretty limited, but Microsoft has nonetheless gone and laid thing out with another handy upgrade guide
to avoid any confusion. The short of it is that those with Windows Mobile 5.0 or 6.0 devices are flat out of luck if they're looking to upgrade to 6.5 (although they may be able to upgrade to 6.0 or 6.1), while users of Windows Mobile 6.1 devices (but not those aforementioned users that have just upgraded to 6.1) may
be able to upgrade to 6.5 at some as yet unspecified point in the future. Right now, that latter group is confined to just eight phones (including the likes of the HTC Dash, Snap and Touch Pro2, and the Samsung Jack and Epix), but Microsoft says more devices may be added at a later date. Still confused? Then hit up the read link below for the complete breakdown, and try to forget about that whole Windows Mobile 7
thing for the time being.
