Re: AT&T users--Please vote for bug # 8240-850/1900 support
 
Sure I'll vote. Would be cool to get 3G from AT&T on this thing. I'm happy as is because I have never had a data package before I got my n900.

bad news. programmers could not
 
hi
I am a GSM user, and even so, I decided to buy this device. I think it is impossible for any developer to emulate 850hz for 3g, then, they are not as good.
I think nokia can not do. very bad for nokia.

I'll vote. hahaha

I believe its hardware so its hardly a bug... I used to be an ATT customer however since I switched to TMO my bills have went down considerably and I believe I am getting better 3G service too (granted not as much converage outside of the city)!

Really dislike ATT, switching to TMO is a savings of approx $30 a month so well worth it...

so you insist that your life must be made as hard as possible? instead of switching operator to other who has standard 3g-frequencies that just work, you wait for devices that work in minority frequencies.

my TMO USA data plans have always been unlimited, but u r saying you have a 7mb cap on att, right?

First, many people do not have the option to change carriers. Either due to lack of service coverage, contracts, family plans or any number of other things. Second, T-Mobile's 3G frequencies are used far less frequently globally than AT&T's. There's nothing "minority" about it.

I think you have that backwards. The N900 is available in the U.S. because T Mobile uses the same frequencies as most of Europe, which is Nokia's main target. Perhaps you meant to say nationally instead of globally?

No, T-mobile USA uses W-CDMA 1700MHz (band IV) which is only used there and in Canada. AT&T uses band II (1900MHz) and V (850MHz), which is also used in South America and Australia. Europe mostly uses band I and VIII (2100MHz and 900MHz).

Naw, I'm saying that I'd rather pay $10/mo for T-Mobile's 7Mb (and soon to be 21Mb) download speeds vs. $30/mo for AT&T's 800Kb. 99% of my life is spent in a region well covered by T-Mobile (and AT&T), so the switch is an easy one for me.

It's just downright silly to log a "bug" for the N900 not supporting a different set of UMTS frequencies.

Frequency support is hardware locked. You want a different set of frequencies, you get a different hardware model.

That's why we have a Nokia N95-3 that supports AT&T's USA 3G frequencies as a separate model from the Nokia N95 that supports the standard European set of 3G frequencies.

Last time I checked, in the USA anyway, having a radio transmitter where anyone but the hardware manufacturer could change the broadcast frequency was ILLEGAL.

That's why hardware manufacturers submit their devices for FCC certification on a SPECIFIC series of frequencies. They are then allowed to operate the devices on said frequencies and at the manufacturer's stated transmission power levels.

At the very least, if new frequencies were enabled, a NEW model would have to be re-submitted for FCC certification.
