Compatibility with T-mobile
Ok, so the Blackberry website lists the bands that the Z10 works on as
Up to 4G LTE
Quad band LTE 2, 5, 4, 17 (700/850/1700/1900 MHz)
Tri band HSPA+ 1, 2, 5/6 (850/1900/2100 MHz)
Quad band HSPA+ 1, 2, 4, 5/6, (850/1700/1900/2100 MHz)
Quad band EDGE (850/900/1800/1900 MHz)
Nowhere on the page says that there will be different phones with different bands. If anybody ACTUALLY knows if this is correct or incorrect, please let me know. I am not looking for someone speculating based on past experience with Blackberry. I think we can safely say that nothing is the same after the news of no BIS required. Thank you in advance.
Just called Blackberry Support and they told me that there is only one GSM version. They will not be splitting the bands between different versions. It has all bands.

Edit: GSMArena also seems to indicate two models, separated by the HSPA+ frequencies listed above. The good news is that they're all quad band GSM and quad band LTE.

I have an RFF91LW from Virgin Mobile (Bell). Unlocked it tonight and popped in a T-Mobile micro sim. Works like a charm. Have been able to surf web, text, and make phone calls. Haven't tried BBM or anything yet as I still have not fully transferred everything over from my OS7 phone.
When the phone boots up, I get the TMobile splash screen, 5 full bars and a nice 4G status. Tried out speedtest a couple of times from my desk, and fastest I've gotten is about 4 Mbps down, 1 Mbps up. Mistakenly posted saying I hit 15 Mbps (wifi was on) earlier.
However, depending on where I'm at in my place, it goes from 4G to Edge. I haven't left the house, so I don't know what the reception is like in other parts of town. Will know more tomorrow when I'm out & about in Houston.
So..I can confirm that the RFF91LW works on T Mobile's 1900 MHz band. Next up will be LTE when it's launched.

It should be faster, but I'm probably in a bad spot or something, even though I have 5 full bars. I'll do some more testing tomorrow when I'm in other parts of town. I was hoping for something like 15 Mbps or higher on the HSPA+ network, but not tonight.
LTE is faster, but if you're not on the unlimited plan, it just means you'll hit your data cap faster.

Maybe the speeds would have been better with the RFK121LW model since the frequencies are different, perhaps you are just getting 3G speeds. Here in South Florida I easily get 20Mbps down on HSPA+ on T-Mobile.

Just ran some more tests in various parts of Houston.
Down: 9.6 Mbps
Up: 2.05 Mbps
Those were the fastest I've been able to achieve so far in my limited testing. Talked to one of my sources running on Koodo (Telus). Their results were 13.78 Down, 1.85 Up.

Ran some more tests with a Simple Mobile micro sim. Results vary and they're all over the board. Getting results of 6/1, then move about 3 feet over and it drops to 3/0.75.
Compared it to coworker sitting beside me. On his iPhone (ATT LTE), he was getting 15/16. His upload speed was faster than his download speed!
Another coworker on a Note 2, on T-Mobile was only getting around 2/0.6. I have not gotten anything as low as him.

Here is the listing.
What threw me off is the seller misleading potential buyers by listing RFK121LW's bands, when the pictures clearly show RFH121LW as the model#. I hope nobody from North America buys from the crook.
