I'll always have a special place in my heart for the Palm Treo 750 — my first smartphone. Felt great in the hand. Tremendous keyboard. Great on calls (at least for me). And so I get a warm feeling in my tummy seeing a video like this.

The 750 was passed over for an update to Windows Mobile 6.1, but of course the chefs at XDA Developers took care of that. And now we see a 6.5 build on the venerable ol' phone.

Of course, hacking your phone is bad, unofficial, not necessarily legal, may cause joint pain and loosen teeth, is not safe for small children and some animals, and almost assuredly won't help you with the opposite sex.

But it's nice seeing some new life breathed into an old phone.
