hi, i want to install win XP to my MBP on boot camp actually i have installed vista 64 but, there's a lot of incompatible driver for it for my devices, eg Blackberry, and other phone. anyway i've heard several problem regarding XP SP3 problem on bootcamp, so before i take a jump i just want to make sure. since my OS is 10.5.6 so i guess my bootcamp version is already on 2.1 ( mine is unibody MBP purchased on this december). should i buy XP SP2 and after that upgrade it online to SP 3 ? or Should i just install XP SP3 straight away ? thx for any help, it's really appreciated.
