Well guys, there are many ways to maximize the amount of RAM your iDevice has. First of all, the most basic way to maximize the RAM of your iDevice, is to install as less tweaks as you possibly can.
Here is a guide to increasing the RAM/Speed of your iDevice:
1. Disable spotlight-One does this in Settings>General>Spotlight Search, and uncheck everything.
2. Optimize images in Winterboard-Open winterboard, and look down at optimize themes 1.0. It will say "Reticulating Splines, please wait, this will take a few minutes." Wait until it's done (that message will disappear when it's done ). I typicall optimize ALL theme stuff, keyboard, widgets, everything. Optimizing compresses an image, saving space.
3. Disable unnecessary Launch Daemons: install Mobileterminal for iOS 4. Install Remove LaunchDaemons from that same repo. Go into Mobileterminal, type in "Su" and then "alpine"(or whatever password you use for sshing) and then type in "rld". Press enter, read, and follow directions.
4. Remove unnecessary Language packs: install Mobileterminal for iOS 4. Install Lang2.2 from that same repo. Go into Mobileterminal, type in "Su" and then "alpine"(or whatever password you use for sshing) and then type in "lang2.2". Press enter, read, and follow directions.
You'll need to reboot after removing Language packs or LaunchDaemons. Remember to READ everything that it tells you, you don't wanna remove anything you actually use lol.
Google for the deb, or you can do it manually.
Here's some more ways
By Patfreak: i deleted all my unused language manually..plus all the var/logs/crash and var/mobile/library/crashreporter reporter which one file usually 87kb-90kb..and thats what make mine a incredibly fast.
maybe you want to speed up more.i deleted the female and male voices in System/Library/PrivateFrameworks/SportsWorkoutframework/voices. and just leave ENUS..im on iphone 4 4.3.2..try it and youll see much faster and a larger storage..free up to almost 100mb
You can get much more speed/ram doing the above things. BE SURE TO READ EVERYTHING YOU DO IN MOBILETERMINAL!!
Another way to free alot of memory on your iDevice is, if you own an SD or an HD iDevice, navigate to var/mobile/Applications (This will not free RAM, but actual memory on your iDevice)
In there you will find app folders...Now, in each there will be a folder ending with .app. Now, navigate there and if you are HD, delete all of the SD images in there (you can usually tell by there being two files, one with @2x and one with no @2x...example, default.png and
default@2x.png). Delete the one WITHOUT the @2x in there. If there i an image that does not have an @2x.png pair, I'd leave it alone. If you own an SD iDevice, delete the @2x.png images instead, as they just take up alot of space.
You guys will find that you can free alot of memory by removing all of these extra images

.
And yes, I've tested all of these methods as well..my iPhone can handle widgets much better than before .
Also, be sure to reboot after you do this guys, as rebooting clears your processes better than any Cydia application can... a reboot a day isn't a bad idea, although it might be inconvenient for people who are currently tethered.
*Also note that using heavy hitting themes that require alot of setup will take up your RAM, as they not only use a widget, but tweaks that will get the icons in the placement they need to be gotten into. Therefore, Nav themes or any other perpage setup can guarantee to use more RAM. A complete theme with no special setup, maybe a light widget would be best if you want a quicker iPhone. I get over 360 megabytes of RAM with a lockscreen widget and a complete theme running on my iPhone.
Also, I use omnistat to free my memory...Sbsettings uses Activator, and is a bit buggy on my firmware anyways. Omnistat would probably be better for freeing up memory.
If anyone has any other ideas, please feel free to add them in the comments below, and I'll add it to this post with credit for finding it given.
