Is it normal for the springboard to be super laggy when you put it into "wiggly" mode? I've held my finger on an app and it literally takes at least 15 seconds to start wiggling. This is after a restart and with nothing running. Here's a picture of the screen I was on, as you can see it's almost all the way full if that makes a difference.
I had a similar issue with my iPhone 4. I had around 500 apps installed at the time and it would take a long time to get them all wiggling. I recently deleted 90% of them and brought myself down to 2 pages (And tons of folders removed) and now it's all back to normal, and wiggling doesn't take forever. From the looks of it, you have a lot of apps installed too. It must be an OS limit we've reached and it just takes a lot of time to get them all wiggling. I'd suggest you delete a lot of apps and see if it gets any better. EDIT: And at second look, I see you are jailbroken, so it could be also a memory issue from something you have installed or something, no idea. You've deleted everything from multitasking tray and free'd up memory from sbsettings already?
Yeah nothing running, freed memory, all that good stuff. Probably like you said, just an OS limit. I would delete a bunch of apps, but I have them on device only, not on a computer. Now that I have folders I hardly open them up to play old games, so they wouldn't get played for sure if I had to redownload them. I guess I'll just live with it for now, I usually wait till I have a page or two of apps to put them into folders anyways. Just gotta make sure I have an afternoon free when the time comes
Is it jailbroken? I have the same issue on both my jailbroken iPad and iPhone on 4.3.1 but the benefits outweigh the small annoyance.
I've been having the same issue on my non-JB iphone 4 ever since I was forced to install iOS 4.3. I thought it was doing this because my home computer has a virus but after reading Hodapp's comment, it must be the 800 apps installed. On a side note, I implore the OP to back up your apps to another storage device asap. I've lost many pulled/removed apps from not doing this.
You have just 36 megabytes free on a device with 256, where the OS should normally take ~80. Probably, some installed software has a memory leak and is slowing down Springboard. Try booting into safe mode or restarting.
I had that issue a lot before I Jailbroke my device. It was definitely caused by having 500+ apps on it at the same time (folders worked fine after a vanilla restore with no apps). FolderEnhancer fixed it for me.
