iOS5.1.1 slide to unlock freeze with iPod Touch 4G

[poisoned_dwarf]

From reading the forum, it appears that iOS5.1.1 jailbreak works for some with iPod Touch 4g. Unfortunate to say, I am not so lucky. Disabling all MobileSubstrate components did not improve the lag. I even tried the tethered jb, then performed the Rocky Racoon 5.1.1 deb installation but to no relief (I always start device as new after applying the iOS and jb). I had a similar problem of screen freeze after "Slide to Unlock" as reported in this thread:
iPod Touch 4G White - iOS5 Unlock Lag - SiNfuL iPhone

I did a bit more searching on the web, saw this thread on the Apple Support Community forum reporting the similar problem:
ios 5 make my ipod 4g slow: Apple Support Communities

The 4-5 seconds freeze after "Slide to Unlock", and general applications slow response had gotten to me after 3 days of using the jailbroken iPT4. One thing I noticed that whenever the iPod Touch 4G is connected to the computer, I do not see any of the freezing.

After almost bricking the device (the dreaded kernal panic message appeared), I have rolled back to iOS4.3.3 (may even downgrade back to 4.2.1, which is the iOS I "upgraded" from). I am hoping that the horrible lag is gone.

If anyone had figured out a way to get rid of the freeze after "Slide to Unlock", I would love to hear from you. Otherwise, I guess my iPT4 is at its final iOS version of 4.3.3.

Not sure but I had to remove appCake after upgrading to 5.1.1
Everything seems smooth now.

I have the same problem as you, my main issue is the 5 secs freeze after slide to unlock, i searched and searched all over the net, and no one has seemed to figure out or what is the cause of the problem.

I could recommed installing the unfold app from cydia, it totally eliminates the freeze after slide to unlock, but this has a side effect on the ipod touch, battery drains too quickly, apps crash, etc etc

[poisoned_dwarf]

No sure I want to say that I am glad that not being the only one encountering the issue, as I don't really wish this pain on anyone else. I still find that it is strange that the issue only rears its ugly head after unplugging from the USB cable. Could it be possibly power related to the IPT4G?

Stealth: I have not tried removing the AppCake+. Oh well, too late already for me. I do not feel like doing another jail break...I have already wasted too many hours in the past few days on jail breaking and reinstalling all the apps and tweaks.

Bojo: Good to hear that there is a possible solution by using Unfold app. However, as you have pointed out, battery is going to be even worse of an issue. (How about another unlocking app called PaperLock? Perhaps it is less buggy than Unfold?) I guess I am not regretting the decision to revert back to iOS4.x. Nevertheless, I am already missing the Notification panel from iOS5.

Possibly not enough RAM to run all of your cydia apps. check sbsettings and the amount of free ram that you have left.

Same problem here as well. I am restoring my iPod right now. Lets see what triggers the freeze.
Anyone out with a fix?

Cydia App List:

Installous 5
SbSettings
Apple Congrency SbSetting Theme
Celeste Bluetooth Sharing Application

Mine does it sporadically. Doesn't matter if I'm hook to pc or not. I'm not really bothered by it........yet

[ibby1001]

It is because the available memory on ios 5.1.1 keeps getting low everytime. i also do not know how to fix

[DoublePawn]

I am experiencing the same problem as well. Hope someone finds a fix for this.

[bojo619]

any news? this freeze issue on my ipod is really getting on my nerves...

[poisoned_dwarf]

Unfortunately, no news. One thing I should have checked was whether the lag also affect non-jailbroken iPod Touch 4G.

Since it is getting onto your nerves (it did with me), revert back to iOS4.x will be your only solution, unless you did not have the blob from previous iOS.

Good luck.

hello everyone .

i also had this problem and it got on my nerves as soon as it happed and it froze after every 3-5 mins when i went to unlock it.i also noticed that everyone did not put what software they used to jailbreak there device and i used absinthe 2.0.4 and i jailbroken my ipod 5 times and still got the lag.(FIX) i went and used another jailbreak software called redsn0w 0.9.12b1 and it hasn't ( touch wood ) had any freeze moments. i have a white ipod touch 4G 8GB. i hope this has helped someone with the lag issues because i know how those little 5 seconds can really F**K you off lol.

I used both redsnow 0.9.12b1 and 0.9.12b2 and the freeze still happens...
Lucky you i guess

hi to all, i'm new to this forum. i had this lagging problem in my ipod 4g running ios 5.1.1 (jailbroken) too and i searched the entire web for a solution. but there is none and it seems apple sucked in here!
i think i found a way to remove the f**ing lags. i just disabled the camera button in the lock screen via springtomize 2 (a cydia tweek) and the lagg is gone! try this and feedback the results!

Great Regards...

I get the few seconds lag, and I have found the ultimate 100% working fix for it, JUST IGNORE IT, in the grand scale of life is it really such a hardship to have to wait a couple of seconds to slide a button on a mobile device?

Haha this made my day

[jasmeet10]

i have the same problem, it only happens sometimes though, like2 or 3 times a day. but when im not connected to wifi it is fine. anyway the only solution i got to this is the unfold app from cydia. but i do not use this as it draings battery and would prefferr to normal lock screen.

any other solutions??

[jasmeet10]

this is starting to get annoying, i have reverted to using un fold,

any helpp?

Hey guys, I've been having the same issue with my jailbroken iPod Touch 4g running ios 5.1.1, ever since I jailbroke it. I TRIED EVERYTHING. I'm 99 % sure it's a jailbreak issue because before jailbreaking it never happened. I tried jailbreaking with absinthe, redsnow and snowbreeze (all successful) but the freeze after unlock happened every time, even if I uninstalled every tweak including MobileSubstrate.

I started looking on the web about this and I came to the conclusion that this happens because when you lock your ipod, after a few minutes it goes into sleep and when you unlock it doesn't "wake up" well and thus the stupid springboard freezes for a few seconds which can be incredibly frustrating.

So I was looking for a way so that the ipod would not sleep when locked and I found "PreventSleep" from BigBoss's repo in Cydia, which, well the name says it, prevents your ipod from sleeping, maintaining wifi on too, (even though it's locked and the screen is off like it should). I don't know if it uses more battery but ever since I installed the tweak and kept it on, the freeze after unlock lag hasn't happened again! Once you install the tweak, you can activate it via SBSettings toggles or activator. Hope it works for you too!
