IPCC not installing onto my iPhone, but worked on another iPhone

[RCizzle65]

I am trying to install the ipcc file onto my iPhone, but it won't work, I've tried two different computers. Then I installed it into my brothers phone, and it worked flawlessly. I think it may be a problem with my phone, because back on jailbroken 2.2.1 my phone wouldn't accept carrier setting updates for some reason. Did I mess up my iPhone a long time ago trying to jailbreak it, and is there any way to fix it?
If it helps, the error message I get is (0xE800003D), the page it brought me to doesn't help my problem since I jailbroke it Update and restore error messages on iPhone and iPod touch

Well I found the solution, here it is if anyone else has this problem. AT&T Carrier Logo messes it up somehow I guess, so go into Cydia and remove it. Reboot your phone and update accordingly. You shouldn't get an error message, then go back and reinstall it if you want to.

I'm having the same issue but I do not have the carrier logo installed

FIXED: The carrier folder was owned by root not mobile

I didn't have it installed either. Are you on AT&T or something else? I'm gonna try to fix it now.

I have been trying to find out why I could not update the ipcc all day. Thanks so much, this worked perfectly. Now I have MMS
