Anyone know if this can be used on 3G networks in Europe? I mean for high speed data, not just speech or EDGE.

Im asking since 3G is on different frequencies in US and Europe. My US version Palm Pre for example cant connect to European 3G networks for data use, only speech is possible.

The iPhone is a global GSM phone, so it should work with 3G networks in Europe as well, since it is the same hardware that is sold on European carriers.

Was your Palm Pre purchased on T-Mobile's network? T-Mobile phones use lower frequencies for 3G that make them incompatible for 3G data with pretty much any other carrier.

ok, thanks, that was what I wanted to know.

My Palm Pre has AT&T stamped on it. I got it for free from Palm as a part of a developer program. All I know is 3G data fail to work on it here in Sweden. Making calls work fine though.

T-mobile uses different frequencies for 3G, but some of their phones (e.g. Vibrant) also have 3G in Europe.

Can you tell which these frequencies are? From my previous understanding, while there are many frequency bands for 2G, there's only one for 3G (2100 MHz)

Yes. Iphone 4 supports 3G on 4 frequencies, including 900Mhz and 2100Mhz that are commonly used in Europe.

Where in Europe? iPhone supports HSDPA on 850 / 900 / 1900 / 2100

Sweden

It's the exact same iPhone that has been on sale via Swedish carriers, bundled with 3G/+ subscriptions, for half a year now. You can order an unlocked iPhone 4 directly from the Swedish Apple Store today, no need to import one anymore.
