Whited00r custom firmware (IPSW) was developed to support older models of iPhone such as 2G and 3G and iPod Touch 1st and 2nd generation. The hardware of these older devices is not optimized to run iOS 4.0 and above and many experienced sluggish performance on their device.

Whited00r came along and provides an alternative for these older devices to run on iOS 4.0+. Essentially the firmware is based on iOS 3.1.3 but added with features from iOS 4.0 and above.
Some of the features mentioned on their website:
- iOS 4 user interface
- Multitasking
- Folders
- Wallpapers
- Battery percentage
- MMS
- Tap to Focus (digital camera)
- Video recording
- … and many more
There are 2 versions for each custom firmware:
- Normal – If you can legitimately activate you device via iTunes AND you don’t need carrier unlock (you have the original SIM card or your iPhone is factory unlocked)
- Unlocked – If you do not have the original carrier SIM and need the unlock. Note: Push-Notifications patch is required after the installation. Note: unlocked if your baseband version is 5.13.04 or below.
Both Normal and Unlocked firmwares are jailbroken with Cydia installed.
For each of the above you can choose between Full or Lite version.
- Full – includes all features
- Lite – better performance as multitasking and home wallpaper are disabled

Unfortunately No.. u cant install iOS 4+ apps in this whited00r Custom iOS. :(
correct, because it's using 3.1.3 as a base
I have iphone 3g ios 3.1.3 baseband 05.12.01 and i want to get ios 4.2.1 without upgrading my baseband to 5.14 or 5.15!
will this custom firmware help to keep my baseband where it is and upgrade the firmware to 4.2.1 without loosing my unlock?
do i need to save shsh blobs?unlocked full version will decrease the performance of my fone?
Thanks
4.2.1 will definitely be slower, you can try this as well: http://www.iphonejailbreak.me/update-iphone-3g-or…
if i upgrade my ios 3.1.3 to 4.0 or 4.0.1 will it upgrade my modem firmware?
there's no 4.0/4.0.1 so use this instead http://www.iphonejailbreak.me/update-iphone-3g-or…

Any idea about whited00r 4.2.1 custom fw performence in iPhone 3G ?
hi i have a 3g that was on iOS 4.2.1 now running iOS 4.1 by the use of a saved SHSH file while also running baseband 6.15.00……….i 've tried to restore it with whited00r 4.2.1 using the iTunes application but i keep on getting an 1015 error code…what do i need to do to make this work??? do i need to restore back to iOS 4..2.1 then after that restore using whited00r 4.2.1 and then jailbreak with redsn0w again??? any help would be greatly appreciated : )
can you kick it out of recovery after getting the error 1015?
i don't recall
use tinyumbrella
i think so other wise how would i be able to restore back to iOS 4.1
use tinyumbrella how to kick it out of recovery mode; then, what?????
use redsn0w 0.9.6b8 to pawn DFU mode, then do a shift/opt restore
will redsn0w_win_0.9.6rc8 still work instead of 0.9.6b8 to pawn DFU mode,then do shift/opt restore in itunes? sorry i'm kinda a newbie to this still!!! and thanks a lot for all the great updates and links and so much more!!!!!
yes it would
yea, jia you!!!!
i was able to install whited00r onto my3g, but now when i go into redsn0w 0.9.6rc8 and i select browse it asks me to verify which ipsw to look for which i do then it scans my phone and now it says unable to recognize specified IPSW now what should i do????????
whited00r firmware should already be jailbroken, if it's not for you, make sure you have the correct IPSW: http://www.filefactory.com/file/b542166/n/iPhone1…
whited00r install works on my 3g bcuz i've got the video camera option, multitasking, and wallpapers etc…what do you mean by if it's not for you!?!?!?!?but when i went into redsn0w to verify all the options i got that strange message saying that the ipsw was not recognized….should i still restore it back using the link that you sent to me!?!!?!?!
do you have Cydia installed? Then no need to use redsn0w anymore
yes i have cydia installed on to my iphone but it never asked me if i wanted to make my life easier!?!?!?!
you probably have your SHSH saved already, don't worry
Yea I just saved the .shsh blob but it only lists six of my previous .shsh saves and I didn’t see the newest whited00r .shsh save btw I used tinyumbrella to save the .shsh blob
whited00r doesn't have its own shsh… shsh is based on the iOS version
