Iphone V1 needs replacing, currently using $39 prepaid option, can I use the same plan for 3g? How about the go phone option? I'm not against a contract so much as being locked in for 2 years to a phone...who knows what might come along next. Where is the best place to (safely) purchase? I found Qbelam.com which says 3g 16gb for $369, some canadian company. Comes up as first (sponsored) result if you google iphone 3g unlocked.
