SK4G on AT&T?

Is anybody using the SK4G on AT&T? Lets not start a carrier discussion other than can it get on ATT 3G bands? I believe the samsung vibrant can. Correct me if Im wrong about that.

I doubt you would find anyone using a Sidekick $G on AT&T
The 3G (UMTS) bands supported by the SK4G are Band I (2100) and Band IV (AWS1, 1700/2100).
AT&T uses Band II (1900) and Band V (850) (at least according to http://en.wikipedia.org/wiki/UMTS_frequency_bands )
So while you could use it with the 2/2.5G (GSM/GPRS/Edge) service of AT&T, you wouldn't be able to use it with their 3G network.

Thanks. I thought that might be the case since t-mobile owns the name sidekick and there is no international version of the phone.

Is it possible to flash the radio with one more compatible with the network the person is interested in using:

It has nothing to do with the radio. Its hardware based.

'tis 3G, but either way AT&T's HSPA+ is practically the same speeds as their 3G.
Pretty much no difference.

I tried using AT&T just after unlocking my SGS 4G. It doesn't show anything better than a 3G speed. From my experience, no you cannot get 4G on the west coast in AT&T

[Q] Can my nexus s bought in Europe work in 3G mod of AT&T

Hi, everyone, I am new here in US, and have got an sim card from AT&T. But when I put it into my Nexus s bought in Europe, it cannot work in 3G mod. My phone is i9023, and the radio, or so called baseband is I9023XXKD1
It is already unlocked, and I am wondering if it is possible for me to let it working in the 3G mod of AT&T by flashing a new baseband. Does anyone know? Thank u

Le sigh...
Unless your Euro Nexus has 3G on the 850/1900mhz bands (AT&T 3G bands), you won't get 3G on AT&T.

If this phone is anything like the orignal nexus one networkwise, it should work with T-mobile 3G.

4g data

I was just wondering if there was a way to get T-Mobile's 4G Data speeds working on any custom ROM. If there is, how would I do so?

Tmobile's 4G Data already works on custom roms, out of the box.

I think "4G" on TMobUS is just what everyone else calls H+, or "3G" in the UK.

tmobile 4g (usa) is the same as (eu) 3g/H.
naming it 4G is just marketing bull****. (lte based and gsm based phones dont mix)
as far as i know there is only stil lte-advanced thats real 4G

those are all radio related not rom
i don't know if any do now, but in the near future there will be phones working on 4g and lte networks, meaning the radio will support those bands

I was under the impression LTE is 4G. It's only TMobile US who seem to classify HSDPA+ as 4G. Over here (In the UK) HSDPA+ is classed the same as 3G. Once we get LTE, they brand that 4G.
As far as I was aware, the One S is not 4G (LTE) capable.

S/he asked about Tmobile's 4G data speeds. Not if it was faux 4G or not.

TMobile advertises 4g now but has no lte. They say they are going to upgrade their back end to support lte. I assume that means they are different and are on different frequency bands.

Att is also doing this now.
But honestly, I don't care if I get 4G speeds on a 3g network I'm happy. I'll continue to pay my $30 a month.

GS II Skyrocket: Can't be able to use 2G or 3G

Hey, does GS II Skyrocket have only 4G?? I tried looking for using only 3G or at least 2G but I can't find a way... My samsung was originaly from AT&T but I bought it Brand New Unlocked in Amazon... No matter what I try I can't have 3G! It's not that I don't like 4G, but the thing is... There is no 4G in my country!! I'm from Argentina using Claro. I need a quick answer please, everytime I want to use 3G I can't and the fake 4G of Claro takes away all my credit for calling and texting...
ANY help is appreciated!!

It's just a logo. But it's actually running on 3g. it's utms or HSPA+.
it depends on what your country offers.

Oh thank you a lot!
