Once iOS 8.1 stops being signed then its a risk getting into files like that. And carriers continually change and update tower and carrier settings for certain devices and firmware versions. Don't think it's something manual users should be altering on their own. You could see improvement now but if the carrier decides to change things on their end you could be stuck with many issues.
No pun towards the OP. He's just trying to help others.
I'm just letting ya know about past experiences and possible implications.

these hacked carrier packages usually have a "newer" version, so your phone doesn't detect the official carrier packages and update to that. for example, let's say the official carrier package is version 16.0, this carrier package version might be 16.5 or something

Is everything completely reversible with this commcenter hack?
Cause when AT&T releases voice over LTE officially those with altered carrier settings would be stuck needing a restore.

i do believe it is completely reversible. my iphone 5 on 7.1.2 is still doing fine after reverting it back to the official carrier package. when i tried out a hacked carrier package a few month ago, there was the official carrier .ipcc file to download as well, which I used with itunes to bring it back to normal

i've never actually dealt with upgrading/downgrading the carrier packages from the device, always with iTunes so not sure if that's a factor
 
Compared to the last time I used this hack with Verizon I am seeing slightly better signal and speed. No constant dropping of LTE to 3G inside my house anymore. Definitely worth it this time.
 
Okay, I'm not sure if I missed something. On the part where it says to choose the appropriate patch and then my phone will go through a whole boot process and everything, I have no idea which one to use since it's all in Chinese. Any help?
I'm not seeing any difference in bars or speeds right now so I think I missed something.

Carrier hack patch, get better service/bars from your carrier.

That is just the patch you needed to be able to install the carrier file. Google itweakios carrier hack and those instructions are what I always use.

settings/general/about


what carrier file ya got?
 
Is there somewhere that shows what version the carrier file is for each carrier so we can make sure we are always on the latest?
 
Working here on 6+ with AT&T GoPhone sim. A couple mb faster LTE and at least one extra bar.
 
Already get decent signal and speeds through Telus here in Canada, but gave it a try. Didn't improve anything in my case. But if you do a reset networks in settings, it will remove beta carrier settings and provider one will reinstall on reboot.
 
I want to try this just to see what happens, but I have no issues with speed. Is the general consensus that we can or can not revert back if we experience issues?
 
Loving this in tandem with the 4GLTE lock app on Cydia.

You could always restore the phone, just be careful that Apple doesn't stop signing 8.1.
 
I'm traveling to India this month and will be using a local SIM card. Will this hack affect my cellular reception overseas on a different network? I'm on Verizon here.

Well I dove in, and did the carrier hack. The only immediate difference I noticed is that I went from 3 bars at the house to 5. and at work I would float around 1-2, I'm at 4 right now. As far as speeds go, I actually got about 1mbps slower the two times I tested it. But at work it's actually much faster.
