I have two Euro. HSPA+ only, none of them is rebooting at random. I have a blue 8X and a black 8x. They have different firmware but no reboots. NONE!
Under settings, phone update, switch 'off' download updates automatically. Update all your HTC apps.

I've had my 8x for almost a week and not a single reboot. I suspect the reboots are app related from what I've been reading. The OS is rock solid. Also, I've installed a TON of apps myself and have been heavily using the phone.
Had mine for 4 days. I think it rebooted once but I cannot be sure because I had my finger on my power button :/, so 0 reboots so far.
However I think it has a screen problem O.o it flickrs or something...
