iPhone 4 Coming to T-Mobile This Week?

[Bonds79]

What?
T-Mobile is using 1700 UL / 2100 DL frequency which is the UMTS Specification 4.

While iPhone supports the "2100" UMTS, it is for the Europe/Asia frequency pairing which is 1900 UL / 2100 DL a.k.a UMTS band 1... I don't understand what's the hoopla here...

Until Apple includes 1700 Mhz support, there won't be any support for T-Mobile 3G. As simple as that...

That is probably why Nexus One was released in 2 different flavors for the US market

As far as T-Mobile changing both the UL and DL to use only 2100 that's rather funny because again, the 2100 in the iPhone is only for downlink and I don't think I recall any UMTS specification for 2100 UL/DL in a single stream.

Oh also, technically AT&T is using 820-840 for UL and 860-880 for DL. (Rough number but it portrays the idea of the range). Which is UMTS Band 5 spec.

That said, I wouldn't be surprised if Apple branches out to T-Mobile as well. This will require them to sell a separate version at least for this generation. Maybe they will include the AWS pairing for iPhone 5 and we can buy our iPhone 5 directly from Apple fully factory unlocked... Just like how they start selling unlocked iPhones in Canada this coming Friday

I wonder if this is the T-Mobile iphone!!!!!!
I bet the white iphone will be exclusive to t-mobile for a month or two , just a thought

Probably won't be T-Mobile exclusive

To reiterate, I wouldn't be surprised if they launch iPhone 4 with T-Mobile but it will probably be separate device with incompatible 3G bands (hint: Nexus One). The chances are fairly slim but it's there heh...

Last year I moved from AT&T to T-Mobile and with iPhone 4, I moved back to AT&T due to piss poor 3G coverage by T-Mobile and I will be very excited if this mystery phone is indeed the iPhone 4 for T-Mobile.

The reason is that if they actually launch the iPhone 4 with T-Mobile, next year with iPhone 5 US should be part of the common sense group of "iPhone countries with multi carriers" which includes Canada, much of Europe, and Asia... This will entail Americans to purchase iPhone direct from Apple fully and officially unlocked (yes at full price too)...

But somehow the tingle inside my brain said that it's probably another Android device Nobody should be holding their breath heh.... It will be out when it's out

Read what "illutionz" posted above and learn a bit.

You don't seen to read, and I'm really tired of trying to explaining it to you.

Do you even know what AWS means? do you know the diference between the 1700 and 2100 AWS band in the US compare with the same bands on UMTS on Europe??

I know where t-mobile operate, I know very well the diference between those spectrums, and I also know that the current Display spec of the iPhone doesn't show support for those band, That doesn't meant that the actual hardware radio inside the phone doesn't support it. all I am saying is that since there is no official documentation on that chip, and due to the unknown markings one it, there is a "chance" that the chip actually does suport them (it won;t be to hard to accomplish, it's not like making the radio send some weird and unrelated modulation like FM). There are contracts, and certification and legal issues that would stop companies from advertise any support on other "out of contract" networks.


I don;t think it will happen this week, it may o even happen this year but is technically possible to happen sooner than later. (there are many many other reason why something like that may be delay, as an example mac OX was compile to run on X86 arch well before it actually made the change, due to licenses issues with the PPC arch)

Yeah, if you really believe that I got a bridge for sale

Meh, i doubt anything will happen before 2012.

Sure, the contract could have been breached or amended, but I just don't see how AT&T could do something that would lose them iPhone exclusivity unless it was out of their control.

One of the tear downs indicated that the chip could operate in all five frequency bands, but only four at one time or it was firmware limited to four bands. Forget the details, and not worth tracking down.

Point being, if Apple chooses to do a firmware update, they can support the 1700 band. What they may have to give up to make it work is unclear; would the phone be able to roam ROW?

This is NOT like the old talk of an LTE hybrid chip, which is another year or so out.

Don't get me wrong, though-- from Apple's perspective, the only reasons to add T-Mo are higher subsidies or an opportunity to eliminate problems with ATT. I doubt seriously this will happen until the end of September at the earliest.

Read for yourself what the i4 supports:
http://www.apple.com/iphone/specs.html
Cellular and wireless
UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz)
GSM/EDGE (850, 900, 1800, 1900 MHz)
802.11b/g/n Wi-Fi (802.11n 2.4GHz only)
Bluetooth 2.1 + EDR wireless technology

So what you are saying is that they would obviously have to make a specific changed version that will work with Tmobile USA and the rest of the world also. Cause obviously the currect models dont support their 3G.
That we will have to wait and see but I hope you're right cause I wouldnt mind switching to Tmobile for cheaper plans and they also have fast 3G in my area

Hold on, I thought the iPhone had a pentaband chip, as in penta=5, but I only see 4 bands listed there unless I'm missing something.

 

[TroyBoy30]

simple answer? NO!

 

[SAD*FACED*CLOWN]

If a T Mobile launch was as close as the OP thinks we'd have pricing leaks, and some details about the device which would no doubt be undergoing testing RIGHT NOW or would have been tested earlier this summer

From Wikipedia:

According to the FCC documentation filed by Apple, the radio inside the device supports; 800, 850, 900, 1900, 2100. The 800MHz frequency, which is most commonly used in Japanese mobile phones, is not advertised as being supported by Apple.​
