Does the Qualcomm "Gobi" MDM6600 wireless chip support the 1700 MHz AWS band that T-Mobile USA and some other foreign carriers use for 3G?

It may support the frequency but the Verizon won't work with T-Mobile 3G

Huh? It supports the frequency. Apple would more than likely use the same chip in it's next phone. That means the AT&T model. What else does that mean? An iPhone on AT&T that can be jailbroken/unlocked and used on T-Mobile while using their 3G network. Equals? Very happy T-Mobile customers who have been dying to use a proper iPhone on their network. I don't see why Apple shouldn't offer T-Mobile the phone. Their commercials make it obvious they want it pretty badly.

Doesn't matter. If it has AWS, then I can use it with T-Mobile.[/QUOTE]

It does matter. If apple hasn't turned on that frequency in the radio chip firmware, then you certainly won't be able to use it.


If apple doesn't have a reason to turn it on (AKA, no business/licensing agreement with t-mobile), then you're up a creek.

The baseband can support all frequencies but you need the corresponding RF chip and power amps for those frequencies...that is decided by Apple. VZW doesn't have C2K deployed in AWS so i doubt the VZW iPhone can use those frequencies.

If the iPhone 4S will use the MDM6600 chip, how come it's tech specs on Apple's Web site mentions nothing about 1700 MHz nor AWS?

Because it doesn't matter what a chip _can_ support, if the device it's inside wasn't built and programmed to use it.

For instance, the first Verizon iPhone had a dual mode GSM+CDMA chipset, but there were no parts (filters, power amps) or software to enable the GSM side to work.

Likewise, the iPhone 4S must/might be lacking the same for the GSM 1700 band.

It's probably disabled in the iOS. Ask the hacking community for help.

On the contrary, the iPhone 4S has both the sim card slot feature and a new MDM6610 chip. An upgrade from the iPhone 4.
