N1 unlocked dual carrier

I was reading that if you bought a full price out of contract n1its unlocked and can be used on either at&t or tmo. How do you know if its the dual carrier version?

Re: N1 unlocked dual carrier

With At&t and T-Mobile, their 3G is different bands. Edge should work on both carriers, but the 3G is carrier specific and there's no way to change that since its hardware related within the radio.

Nokia just recently released a phone that has quad-band 3G support, so hopefully we'll start seeing that more and more so that we can easily swap between At&t and T-Mobile and get full 3G.

Re: N1 unlocked dual carrier

I think every GSM phone can get Edge as long as its quad band, which most are.

3G is the difference though, because up until that Nokia phone, they all only supported 2 bands for 3G (850MHz and 1900MHz for At&t or 1700MHz and 2100MHz for T-Mobile).

apparently the unlocked nexus does have the radio bands for tmo and at&t 3g but its missing an amplifier for at&t 3g. That's what was confusing me until I found this article. xe

Re: N1 unlocked dual carrier

That's an interesting write up, and I've never seen it before. Makes you wonder why they didn't just add the chips necessary to support all the frequencies.

Nobody on here, XDA, or AndroidForums has ever said anything about getting all frequencies to work, so I doubt its possible without hardware modifications.
