Upgrade on three
I got mine in a 2 working days, ordered it on a sat and got it on a tues (three ireland) not too bad i think absolutley love it, so refreshing tho fast, and smooth and the interface is a brilliant change!
dont know if they use the fb intergration numbers or a facebook app that you get from the marketplace
personally i dont like the application im just using the mobile web page,
seeing as its not mulittasking, the facebook app doesnt seem to tombstone properly ( ie save where is was and resume) although there is plenty of documentation on how to tombstone your applications so you pick up where you left off.
