Cydia is a replacement packaging and repository manager for the original Installer.app for the iPhone or iPod touch. It was created by Jay Freeman to replace BSD Subsystem and Installer.app. Cydia is a UI frontend to his Open Source APT for Debian called Telesphoreo. Cydia pomonella is the scientific name for the codling moth, which is what we often think of the as the stereotypical apple worm.
To get Cydia you need to have Installer.app already. Then just add http://apptapp.saurik.com/ as a source to Installer and install the package “Cydia Installer” from the “System” category.
Cydia itself looks similar to Installer.app but add many improvements to organization, functionality and performance of Installer. With Cydia you:
See the number of apps in each category
See details of what installing each app include such as file size and functionality added
Search for apps by name
See changes to your currently installed apps and available upgrades
See details of currently installed app and easily manage them
Currently with the release of the iPhone 3G which comes with OS 2.0 and the related iPhone pwnage tools many of the apps written for the older Installer.app have to be ported over so developers are working on that. In the next few weeks you will start to see more and more apps in Cydia with lots of cool new features, so check back often.
Note: The quick and easy way to get Cydia on your iPhone is to install it using QuickPwn.
Update: For Windows users with the iPhone 2.1 software update, you can get both Cydia and Installer on your iPhone really quickly and easily by installing the QuickPwn software on your Windows PC. The entire process is streamlined and takes only a few minutes.
Update: Ultrasn0w for iPhone 3G or 3GS is ready. You can now jailbreak and unlock your iPhone 3G or 3GS with OS 3.0 firmware.
1. Ensure you have upgraded to iPhone OS 3.0
2. Jailbreak your iPhone 3G using redsn0w or PwnageTool & if you have the 3GS use the purplera1n installer app to jailbreak it instead. (after this step you will have Cydia)
3. Run Cydia
4. Add the repo repo666.ultrasn0w.com to Cydia. (that last o is actually the number zero)
5. Search for ‘ultrasn0w’ in cydia and install ultrasn0w
6. Reboot your iPhone 3G
7. T-Mobile USA users should disable 3G before using ultrasn0w
Update: Purplesn0w can also unlock your iPhone 3GS, so use it instead of Ultrasn0w if you wish. The steps are exactly the same as the above. Only use this repo source in Cydia apt.geohot.com and install Purplesn0w from there.
Update: If you have OS 3.1.2 you can use blackra1n or PwnageTool 3.1.4 to jailbreak and get Cydia installed on your iPhone or iPod touch.

Ok .. I used cydia to get app called winterboard. Then I got another app from Themes (springboard) and I used it to change the look of my iphone. That worked perfectly, but now I cant dial out. I can only dial by using the contacts, but not if i wanted to dial a number thats not in my contacts what shall i do ?
And yeah most apps on Cydia or Installer are free but some aren’t like Swirly MMS cost but most are free. I guess Cydia doesn’t like buying apps, this is the reason most games are in the App Store. Because people want to make a profit.
Do we need to pay any app from cydia or it’s free?
Okay guys I just want to help you guys out here, Ive been reading above and a lot of you have a lot of questions. So if you want to alter your springboard (home screen) as in make a user wallpaper appear under your apps, get a new theme, or anything like that, you HAVE to jailbreak! Meaning if you have a Windows computer then you would use QuickPwn or WinPwn (which is normally more favorable to unlock and vice-versa with QuickPwn and Jailbreaking) so to jailbreak you run QuickPwn and the program will walk you right through it unless of course your a total noob. If you don’t trust my word then go to YouTube and let a video follow you through it. The same is with WinPwn but you can go a little more in depth with changing boot logos and the like. If you have Mac then you would use the Pwnage tool, which is much more stable that, of course, windows programs of the same nature. You can also unlock with it. Jailbreaking WILL void your warranty with Apple but in the longrun it’s definately worth it! You can Cut&Paste, MMS, Video record and many other things good old Apple refuses to allow for some moronic reason. And if the iphone ever does brick (freeze And become usless) you can almost always use the restore option in iTunes. After that you can just re-jailbreak and that should go smoothly seeing as I’ve jailbroken the iPhone (2g and 3g) a lot of timesAnd never had a brick.
vomito??
Problem solved for me, in case anyone needs to know. Backed up all data by syncing with iTunes then restored to latest firmware (2.2.1) then ran quickpwn again. Cydia works fine now! Had to dl all cydia apps again tho
I don’t get it. what do you guys mean by backing up your phone?,and I am still thinking if I should jailbreak my iPhone or not. also noticed that some of you guys have problems using it.
plus I’m using the iphone 3G version 2.2 and ive read somewhere that they need the 2.1 version for iPhone 3G ?
Is it really true?,
I can see quite a few people have the same problem I am getting, which is that we have successfully jailbroken iPhone 3g’s and have been using installer and cydia fine but it has just stopped working for some reason with the error message “cannot open source”. I am guessing their is a problem with the source as I can load other sources okay. I am just waiting to see if this will sort itself out. If anyone knows what the problem is, please post here, thanks! I ran quickpwn again, which worked okay but still can’t download Cydia updates.
so you have to jailbreak your iPod to get cydia
hey guys how i get cydia in my iphne icon please tell me cancinocesar@yahoo.com
“No, it’s perfectly legal.” this is incorrect you are modifying a copyright protected software. You have a license not an ownership. However apple will not stop people because then sales would drop. So it is not legal but i will do it anyway.
Go to the top of this website, and search for an app called QuickPwn, its a piece of cake
how do i download cydia plz iv been trying to find out for weeks
Ok yesterday i jailbroken my iphone everything works good and the app store is good nothing wrong with it. But your problem about the apps u downloaded before. Yes the hole jailbreaking thing resets your iphone so you must have backed up your i phone before u had jailbroken it so u can easily reconnect your iphone again after jailbreaking it and the itunes will sync the games and the music and the contacts that u had before on the iphone before u jailbroken it.Besides that the iphone works just fine.Need any further help

Hey guys I have a quick question. If I jailbreak my phone, will I lose all the apps I have already downloaded? And will I still have the app store? Ty
Hey there! I am also heavily researching jailbreaking my IPhone. So you’re glad that you finally did it, huh? Now after I jailbreak….. is the Apple App Store still there and accesible? And all of my previously donloaded apps from the app store? do they still work on a jailbroken phone? and if so, do i have to download them again? does jailbreaking your phone pretty much “reset” it? can anyone please let me know. I’m really weighing my options here.
