Right, I'm late to join this thread but I'm looking at getting an Iphone4.

Can anyone who knows a bit about it all tell me if there is anything I need to know before I go for it.
I'm on Virgin but have just found out they don't do it so I guess that is ruled out.
Anyone know any good offers? So far O2 looks good.
I don't want to spend more than £25 to £30 a month maximum.

Thankyou.
