Unlocking Palm Pre Plus possible?

[Incubated]

i recently broke my touch diamond. i am quite happy about it. i have wanted to get a new phone for a while, and diamond was pissing me off too much. anyway, now that my provide is HSPA and supports sim and cdma, i was looking into palm pre plus as my next phone. webOs seems to be very much what i am looking for, and with the hardware improvements made to the pre, i think the phone should be a good one. if i am wrong somewhere, or am making a mistake in getting the pre plus, please let me know.

so, is it possible to unlock an att phone on a canadian network without shelling out $50? can i unlock it, or does it require special hardware?
