Apple releases updated iOS 5.1.1 build for GSM/AT&T iPhone 4

Apple has released an updated build 9B208 of iOS 5.1.1 just for your handset.

There doesn't appear to be any information from Apple on what triggered the new build, though it's possible some very specific bug or glitch was identified and fixed. If it was incredibly minor, Apple would likely just have filed it away for next time. If it was incredibly major, Apple would likely have pushed it out as new update to ensure every user got it.

As it is, if you've already updated to iOS 5.1.1 you won't see the new version popup as an over-the-air (OTA) update, or as available in iTunes. If you haven't already updated, you'll be offered this new version when you do. To force an update from the previous iOS 5.1.1 build to this one, you'll have to restore to it in iTunes. (And really, there's almost certainly no reason to do that.)

iOS 5.1.1 was originally released on Monday, May 7. As of May 15, almost 74% of iMore readers had already updated to iOS 5.1.1. Today, one of the major reasons many had waited, an untethered jailbreak for iOS 5.1.1, was released.

Apple releases updated iOS 5.1.1 build for GSM/AT&T iPhone 4

I'm gonna give this a try and see if it fixes the battery life glitch. Its so bad I'm desperate to try anything that'll help fix it. Im not home now and im trying to watch the hockey game on my iPhone 4 right now and it's going down almost 1% per second and I had to stop so my battery doesn't drain completely. Yeah it's that bad.

I don't think it's a hardware issue. My battery was fine until I updated to 5.1.1. Now I have to carry my charger around just in case. Feels like I'm using an LG android phone :(

Have you tried deleting all your email accounts ? Then reinstalling them. That always fixes battery issues for me !

Mine did that after I brought it with me into the bathroom while i took a shower. In my case it must have triggered the moisture sensor and killed it or something. When it finally drained it would not recharge and turn back on. Make sure you backup, just in case. Apple replaced it for me no problem.

I've been having issues with my phone losing signal until I reboot since I upgraded to the original version. Hopefully this fixes it and there's not something physically wrong with my phone.

As you already have 5.1.1 this update is not applicable for you. However, every software update removes your jailbreak

This minor update does not appear to affect the jailbreak. Just jailbroken my 4S and honesty I don't see the issue with the battery.

I think I'll just wait for iOS 5.2. Or the "new iPhone" with factory-installed 6.0.
Whichever comes first.

Some people clams that it is a "3G to 4G" update, the battery life is horrible ever since I updated to 5.1.1, it feels like it drains battery life really fast but who knows

if I update my iPhone4 from 5.0.1 to this new version, can I still jailbreak untethered? I haven´t updated yet as I´m on vacation without my macbook.

I have had terrible battery life since 5.1.1 update. In the past I charged every other day. Now it's at 20% at end of 8 hour work day. Started from the day I updated.

I have terrible battery life since getting moving from the 4 to 4s period. Regardless of which iOS version. The battery life has just sucked. I need to charge at least once a day. If I use a little bit of video streaming, then easily twice per day. May iphone case is now the energizer battery pack case which just give more power, but is bulky. No choice.

I updated my ipod touch to the latest version (this version mentioned above?) and now I can't get the latest jailbreak to work :( I'm suspicious if it was to prevent the latest jailbreak.....

Hey guys, you can update to this and still jailbreak with no problem. Thing is, you need a DIFFERENT VERSION of the Jailbreak...which you can find in the same website's upper-right hand corner.
You're looking for Absinthe v2.0.1, not v2.0.0.
You're all welcome.

FOr those having pure battery life, try doing a restore using dfu mode as my battery life became awesome after doing that. I didn't even know there was a flaw until I was getting amazing battery life.

DO NOT UPDATE TO LASTEST BUILD OF 208 it will prevent jailbreaking even with 2.0.1 you need to manually download select the the 5.1.1 206 build ipsw & do a restore for the jailbreak to work. HURRY BEFORE APPLE STOPS SIGNING CERTS FOR THAT BULID OF iOS 5.1.1

Dude!!! Thank you so much you saved my ass!! Apple would've effed me over again if it wasn't for your post! Thanks a million!! :D
