Has anyone received the T-Mobile Carrier Update yet?

[darricksailo]

This update didn't change anything that would affect speed. What do you mean? All it did was make it display 4G for HSPA+.

I heard the MTU size change increases speed because it's more optimized for T-Mobile's network. I don't know how accurate that piece of info is though.

Just in case everyone is wondering, I dissected the ipcc file. It looks like it does the following:

All Iphones:
- Enable Visual Voicemail
- Set up new Web APN (Fast.t-mobile,com)
- Set up new MMS APN and server (fast.t-mobile,com, http://mms.msg.eng.t-mobile,com/mms/wapenc)
-Sets MaxVideoBitrateSize for MMS to 131,072
-Sets MaxMessageSize for MMS to 1,048,576
- Enables MMS while you are roaming
- Enables non-iMessage group messaging and Sets the maximum number of recipients to 20
- Set up new tethering APN (pcweb.tmobile,com)
- allows user to edit APNs for internet and MMS.
- Enables and configures emergency alert services broadcast messages (AMBER Alerts, Presidential alerts (whatever that is), and emergency alerts. The sound is set to cvs_alert_us.m4a
- MTU size is set to 1460 instead of the default. (I am assuming 1500 was the default)
- Max Bluetooth Modem Connections (for tethering) is limited to 5 devices.
- OTA Software Updates under 157,286,400 bytes can be download via cellular.

iPhone 4S & 5 Only:
- DataIndicatorOverride is set to 4G. So when you are on the HSPA+ network, it will show 4G instead of 3G.

iPhone 5 Only:
- Enables AWS LTE (user can enable/disable as needed)
- Enables HSDPA+42
- Enables HSUPA 5.76 Mbit/s
- enables the EFR (HD voice) codec.

I don't know if this method works or not. I personally didn't update my carrier settings and don't feel like risking it. Tell me if you give it a try and whether it works or not

I'm currently jailbroken, so I don't think ill be restoring it. If anybody knows of any good tethering apps, preferably a free one that would be great.

I'm doing a factory restore on my phone. Disabling tethering on a phone that originally had the feature available out of the box is unacceptable.

I installed thetherme on my 4S and can tether.

I thought it was to give us LTE?

EDIT: Yeah, it does. There's an "Enable LTE" feature now in Settings > General > Cellular.

Except, Tmobile LTE sucks.

My IPhone 5 from Verizon has the LTE tab enabled. Will my iPhone get LTE?

Sure, but it will say LTE. Those expecting speed increases because it says 4G instead of 3G don't always realize that is just a display change not a speed change.

Latency is a bigger factor and there's nothing T-mobile can do about that. I wouldn't expect that minor change to make a measurable difference.

Nope because the Verizon version doesn't support the band that T-mobile uses for LTE.

No. The Verizon iPhone supports a different band of LTE than the one tmobile uses

I have an unlocked AT&T iPhone 5 that I use on AT&T. If I pop a t-mobile nano sim in and accept the carrier update, will it screw up any settings I need for AT&T?

No. I did the same.
