Unofficial HP iPAQ hx4700 update

HP hx4700Now that Windows Mobile 6 is shipping, let's take a stroll down memory lane and reminisce about the problems users had upgrading their Windows Mobile 2003SE devices to Windows Mobile 5.0.

Specifically, Dell Axim X50 and HP iPAQ hx4700 users found themselves in a bind. They'd already purchased some of coolest PDAs on the market. They had blazing fast 624MHz processors and high quality VGA screens. But since they didn't use the same type of RAM as newer Windows Mobile 5.0 devices, it turned out that when you tried to "upgrade" either model, you'd wind up with a much slower system.

Late last year, Dell released a fix for the Axim. And while the X50 series still feels more responsive running WM2003SE than WM5.0, the difference is much smaller than it used to be. And you get updated versions of Mobile Office and the ability to run newer third party software.

Unfortunately HP hasn't released an official patch for the hx4700. But it appears some Russian hackers have. Werner Ruotsalainen reports that the unofficial ROM upgrade vastly improves performance on hx4700 PDAs running Windows Mobile 5.0. However, the upgrade does not include support for A2DP Bluetooth audio, so if that's important to you, it might be worth waiting (possibly forever) for an official update from HP.
