Will Unity support the Playstation Phone? If so when will that be? Would it be wise for Unity to support the Playstation phone?
I have read that the playstation phone is going to be android based, so yes.
not needfully, only if its hardware is compatible.
android isn’t android, there are specific hardware and compatibility requirements to work out.
If they use a snapdragon for example, chances are pretty high. but if they use others it might or might not work out of the box
According the the leak (which may be fake), it uses a 1GHz Qualcomm MSM8655.
Something else to note is I’ve heard about a psp 4000 (Which has been rumored to be basically a psp 2) Support for that would be very nice 
. but these are all still only rumors. We’ll probably find out come E3.
That would be the new monsters. For PSP performance like a quantum jump (a magnitude to two faster than the previous).
Unsure if the new monsters are compatible out of the box but for them its at least granted that the support for the hardware will definitely happen as it will on android be one of the two major players spring 2011 (with Tegra 2)
