there's more phones with 1900 umts than 850 umts.
lots of phones have 900/1900/2100 umts 3G.

pharos 137 -1700/1900/2100 hsdpa
sony x1i -900/1900/2100 hsdpa
asus p835 -900/1900/2100 hsdpa

Quad-band GSM is different. 3G / WCDMA / UMTS is a separate network from GSM, with separate band support in each phone.

Many AT&T phones are:
GSM 850/900/1800/1900 (quad-band)
and
WCDMA 850/1900 (dual-band 3G)

Hey Rich I'm confused about something. You say that there is seperate band support in each phone, but yet both GSM & 3G use 850/1900mhz. Same frequencies.

Btw, I noticed on Twitter that you live in Pa, I'm from Ct. I'm going home in 2wks for my 30th Bday.

Exactly correct.

I meant that each mode (technology + band) is distinct. For example, there are tons of phones for Europe that are:

GSM 850/900/1800/1900 and WCDMA 2100

In other words, just because a phone supports GSM 850, does NOT mean it supports WCDMA 850, even though they use the same exact frequency band.

I know this is about this perticular news article, but I was wondering might you know when fast charging technology will reach the cell phone market. I'm talking like from completly dead to completly charged in like 20 minutes. Might you know?

i bought a 15 minutes AA and AAA charger few month ago, if they can charge AA/AAA in 15 minutes. what takes them so long to make it charge cellphone??
...

Aren't they different technologies? Batteries are alkaline, and cell phone batteries are lithium ion, perhaps that has something to do with it.

I'm glad your using rechargable AA & AAA's, rather than throwing batteries out all the time. I don't really use AA & AAA's anymore with the exception of my tv & Blu-Ray remotes. Don't need a cd player, I use my N95 for music (and everything else).

But I bought my first battery charger way back in 1995.

Better to balance out the usable spectrum and fill in the holes than to have it all on the 2ndary spectrum

Hmm.... isnt the 900MHz the same as the 850 band they just improved or are improving?
...

No.. 900MHz is Europe/Asia/South America
In the US, some of 900MHz was what is used by some home electronics (old cordless phones) and other parts are used for other uses.

Yeah for those who STILL use cordless phones. 20% of U.S. households are wireless only now. Go wireless! ! !

Hey some of us use landlines, to fend off the telemarketers.

To fend off telemarketers all you have to do is register your # with the National Do-Not-Call Registry, here's the #
1-888-382-1222

I'm sure you can register #'s online also.

i looked up that website to see what it is all about and noticed its a service you gotta sign up with. do you know of anywhere that you can do this for your cellphone service? a friend of mine just recently is getting a PRIVATE call every 5 minutes on her cell and no one is saying anything on the other line, so its real annoying.
she wants to block private callers so they cant call her at all....

All AT&T 3G phones have WCDMA 850. AT&T picks what 3G phones it wants to offer directly, and the manufacturer adds WCDMA 850. It's never a problem; it doesn't limit AT&T's phone selection.

You're talking about unlocked phones. AT&T is never going to make any network decisions based on what's available in the unlocked phone market. There's no business case for that. Sure it would be nice, but it's just not realistic.
