The P4000 from Telus (Canada) is running Windows Mobile 5, unlike the same devices that are being released in the US with WM6.
There are no official announcements about whether or not an upgrade to WM6 will be available or not, but lots of rumors...

I've already seen some confusion in this forum on the part of P4000 users who don't understand why they can't use all of the same themes / hacks / software etc..
I've started this P4000 specific thread for those of us who are stuck with WM5 (for now, I hope) to discuss issues, tips, etc.
Hopefully the forum mods will make this thread a sticky and/ or add a link to the "PPC-6800 FAQ's sticky" to help diffuse the confusion.
