this is a great read for noobs. btw it's a bit irrelevant coz:

1) we don't use at&t, sprint and verizon here
2) most likely people from here will rather go for the prepaid / unsubsidised version, coz u can't grab the contract unit without signing any contract anymore

so the comparison doesn't applicable at all for us malaysian iPhone users. and almost every people here already knew the price for unsubsidised units will be higher. it's common sense.

and yeah u can refer at the pinned thread and also threads on AT&T and Optus prepaid iPhone offerings.

have a nice day.
