I see that T-mobile has an officially launch date for the 9900 but ATT seems to have no date in site with that said will an T-mobile 9900 unlocked work on ATT including there 4G network? or Will i have to buy a Rogers model from Canada?

Thank you

[Fubaz]

no
EDGE only

a Rogers, Bell or Telus one from Canada will work

It will work for EDGE speeds only. For 3.5G/4G you'll need one with the ATT bands which would be Rogers, Bell or Telus.

T-Mobile's 4G claims are so bogus.... it's not just T-Mobile but they are the worst with their marketing BS.

Thank thats what i thought

The specs on the unlocked 9900 UK version that I bought from Expansys are the same as those on Rogers - 850/1900/2100. I just checked on their Rogers and Vodafone websites.

In the past the answer has always been no -- but with the pending takeover didn't they design the 9900 with both 3G/4G bands?

Not relevant with this topic -- but even if it's not '4G' it's still faster.

taubmax- Among GSM providers, AT&T is 850/1900. T-Mobile USA is 900/1700. Every stripe of T-Mobile in Europe is 2100. In North America, models sold by T-Mobile in the US and Wind/Mobilicity in Canada will be 900/1700/2100; those sold by AT&T in the US and Rogers/Bell/Telus/Virgin Mobile/SaskTel etc in Canada will be 850/1900/2100.

I have a BB Bold T-Mobile branded on AT&T's network. I've picked up a "4g" signal as indicated in the status bar. I ran a speed test and got ~4mbps download, which is lightyears faster than edge. I was surprised because of everyone on these forums saying it wouldn't work, but it does for me.

No one has any input on this? It would sure make this purchase easier.... In the past they have been exclusive, I know. But is this one different?

You're incorrect. T-Mobile uses 1900 in the US for 2G and the AWS bands (2100 and 1700) for 3G and 4G.

While yes, Tmo did start it, AT&T is the same technology that Tmo is using. Its all HSPA+. Going back a few, LTE wasn't 4G either, but the standards body pussed out and made them all 4G.

I see you made it on here Rob, good call. You may want to sell that 9810 on ebay and hold out for T-Mo's Torch 2

T-Mobile internal doc leaks, BlackBerry Torch 9810 to bow this November? -- Engadget

I believe that's your only option if you want "4G"

*edit: Look at the 9900. It's available now on Tmobile and it's 4G

Wait - so the above post says att uses 850/1900 and 2100 for 4g. This info from tmobile indicates that the tmobile 9900 should work on att 4g?

I would really like someone who knows to answer this question for me as well.

[palomartian]

It has been answered. See post #2.

So that means the information on T-Mobile's website is incorrect.

[fazluke]

Just listen what palomartian told you and T-mobile site is correct. But to explain all the details about the difference between up/down communications and the various frequencies will take more space.

Again to simplify AT&T "4G" and T-Mobile "4G" are not the same so you can't mix devices between the two networks and expect the same speed.
