Hey everyone,

I'm new to these forums so I hope i'm posting in the right subsection.
I am considering buying an iphone 3g and I hope someone here can help me answer these questions..

1) Are these phones that vodafone is selling for $979 without contract unlocked since they are prepay?
In other words will I be able to use the iphone with a simcard in Europe or are they locked to vodafone nz only?
If they are unlocked, what would happen if i jailbroke the iphone, would it still be unlocked or would it mess it up?

I am really confused as I've heard a couple of conflicting things about prepay. Vodafone's official line is here (  http://vodafonenz.custhelp.com/cgi-bin/vodafonenz.cfg/php/enduser/std_adp.php?p_faqid=6513) , 

 but I've heard from some people that everything except 3G works with a prepay SIM.

2) Another thing, do you think the price of this thing will go down in the next 6 months for prepay or you recon it will hang around 1000 until the next version is out.

Thanks in advance hopefuly someone knows a little more than me about this device..
