You misunderstand... What I meant was " Is 3G backward compatible for
data with previous formats." Plus, i thought that only the US had any
kind of cell company which uses cdma. I am quite surprised by that as I
thought most if not all other countries used GSM. /shrug.

showed them how to make them work in the US.
Means nothing. Their phones may be GSM-capable spesifically to work
overseas. All of my info says that there's no GSM in Japan, but I
haven't rechecked recently
Does EDGE fall back to gprs? Does 3G fall back to EDGE or GPRS if the
phone doesn't support it?
Given a phone that supports all of the following, HSDPA will fall back
to plain old UMTS will fall back to EDGE will fall back to GPRS,
according to network availability. Japan, on the other hand, uses their
own types of (W)CDMA networks.
"3G" falling back to EDGE or GPRS if the _phone_ doesn't support it is
rather nonsensical notion. If a phone is a GSM phone, it will work in a
GSM network. It will not work in a 3G network, so there's nothing to
fall back _from_.
