^ This is a known "problem" with phones unlocked and purchased from USA. Some countries adopt differnet number phone formats for SMS/phone calls. It of course will be fine with FW1.1.1 - but as a fix (and if u want to stay on FW1.02) check out forums on HackinTosh - search for "international phone number" and you will find a patch to correct this (i.e. you can leave all your phone numbers in contacts as 07.... or 01.... etc and patch will update iphone software to also match against +44 7... +44 1... etc etc)
