Also iPhoto only works on 5.1 or above. I tried changing my iOS version in the plist file but then it meant certain tweaks on cydia wouldn't be on my phone since it's 5.1.
Before installing any apps/tweaks, is there a way to check if they are compatible with 5.1.1? Does Cydia inform you of this or not?
My battery seems to be fine and not really crazy about those minor improvements with 5.1.1
I might stay at 5.0.1, everything runs fine the way it is right now.
I tried that a long time ago so I can't remember but I think as soon as the tweaks page is done loading it gives you a warning saying it's incompatible with your version.
Not entirely. Even when apps/tweaks are compatible, there is a red "Warning about 5.1" box that loads up. It's just a generic "don't update" warning. I have installed several tweaks that had this on the screen and am running them without issue.
The best option is to check the revision history towards the bottom of the page and see if the author mentions anything about "updating/optimizing for 5.1 / 5.1.1". If this is done, then you're most likely safe. I've even gone so far as to email an author to double check before installing.
I just upgraded my 4s from jailbroken 5.0.1 to 5.1.1 and the battery life seems definitely improved for me. And knowing I'll have a JB in another several days I'm happy with my decision, although you might as well wait till they release the JB. I just knew I would instantly JB and wanted to test the battery life before
I was going to do that but while 5.1.1 was downloading I unplugged my phone
Better to wait until the official 5.1.1 JB is out before upgrading anything. Even though it looks very promising and almost a go.....it's better to be safe than sorry!
I usually wait a couple of weeks anyhow and let the "guinea pigs" test it out and make sure there are no bugs/hiccups before I jump in head first.
