    Hi. I've searched around extensively and can't seem to find a simple way to remove Cydia after jailbreaking (using redsn0w .8) and unlocking (using ultrasn0w). The primary reason for jb-ing was to unlock my phone so I can use it overseas. For that, I'm thankful for redsn0w and ultrasn0w, but I don't really need any of the other customizations or apps.

    It sounds like the methods people have suggested are hiding Cydia, ssh-ing into the phone to delete the files, or restoring the phone (which locks it again).

    So is there an easy way to remove Cydia and retaining the unlock status of my phone? I'm open to ssh-ing to delete files, but from what I've read so far.. it's quite messy.

    Thanks in advance!

    Is your fear that someone will download Cydia apps on your phone, or just that you don't like the icon showing? Personally, I'd either just put it on your last page of apps or hide it. It may come in handy some day when you least expect it.

    You are plain foolish to try and get rid of Cydia. If you might need it, it won't be there.

    Just put it on a back page and ignore it.

    If you delete it (others have) and their next post always begins with "Help".

    It's both I suppose. Partly because of all the personal information on my phone (ranging from email to photos to mobile banking). Perhaps also b/c now there's an app on my iPhone that's a little more powerful/unknown that I would like it to be.

    It seems like something is draining my battery life too. Pre-jb/unlock, I could leave my phone idle for hours and not drop a %, but post-jb/unlock (I haven't installed anyting since Cydia and ultrasn0w), I seem to be losing a % every 15 minutes. I'm going to charge it up before I sleep and see what it says tomorrow morning.

    (Something completely off topic.. I lost all my custom wifi networks after jb and unlocking... kinda odd).

    Don't get me wrong. I'm thankful for Cydia and ultrasn0w for unlocking my phone so i can use it overseas. But prior to that, I've been a happy stock iPhone user for 4 months.

    It's on a back page for now, but also on the back of my mind.. :) (It took on my mobile banking's icon instead of the Cydia's icon for some reason).

    I have had battery issues, I always restore to official Apple Firmware, choose set up as new, then JB and UL again, choose set up as new.

    Always cured them for me. But it is some work, but well worth it to get rid of JB gremlins.

    If you are worried about someone using Cydia, do you also worry about Mobile Safari, they are EXACTLY the same thing.

    Change your OpenSSH password, that is the only liability.

    PS: We all have email, text messages and banking info on these phones.

    Also, enable lockscreen password. 3 incorrect tries and the phone locks forever !

    Thanks dhlizard. When you say you restore, set up as new, jb & unlock, and set up as new - Are you basically repeating the jb/unlock process until it gets it right? Maybe I'll understand what you mean when I give restoring a try. Haven't had to to-date..

    How do I change my OpenSSH password?

    Yep, complete redo from ground up, has always got rid of any battery issues I ever had (twice on 2 different firmware versions)

    There is a thread on changing your password here on the board, very easy

    If you haven't installed openSSH, and it doesn't sound like you have since it wont auto install, there is nothing you need to do.

    Cydia is not malware, nor does it have any security holes that I've ever heard of. I can assure you that Saurik, the author of Cydia, has no interest in anything you have on your phone. Please don't worry about Cydia any more than you would worry about any other application.

    Cydia is really no different than the App store. Sure, you need to be careful what you install because not everything is as well-vetted as the App store. And it does allow you to uninstall things that might be essential. Just don't uninstall anything you don't understand and you'll be fine. And it won't do anything on its own.

    Cydia does not run in the background on your phone. Unless you open it, it's just an icon sitting on your springboard. When you close it, it's closed. It cannot be causing your battery problems. Usually battery problems post-jailbreak can be traced to restoring the phone from a backup. I would suggest restoring the firmware, rejailbreaking, then choosing the option to set up as a new iPhone rather than restore from backup. You will lose your text messages and saved data from apps (high scores in games, etc.), but it should fix the battery problem.

    Wifi network information is not saved in a backup. You have to re-enter networks and passwords after a restore. It's a security feature.


    All this said, if you are hell-bent on deleting Cydia, it's very easy to do. You can just open Cydia, go to Manage>Packages, choose 'Cydia Installer,' tap 'Modify' and choose 'Remove.' Cydia will remove itself and its dependencies from your phone. Again, though, I don't recommend it.

    Something else to consider. At some point you may want Cydia to install an app you just found out about. What I would do is install either SBSettings or Poof, both will do this. You can use either to hide applications you don't forsee using without actually deleting them. Poof will leave an icon on your springboard while SBSettings launches by swiping to top status bar. Hidden apps are still accessible by using the built in Search feature.

    Scenarios I can see are:

    - You have an alternate weather app/weblink icon to a weather website, hide the Weather app.

    - You have an iPhone and naver use the Contacts app because the Phone app does the same thing, hide it.

    - You want to use MxTube, for example, because it lets you download YouTube movies in addition to letting you stream the wifi quality movies while on 3G/EDGE. Hide the YouTube app.

    - You use the compass while in Maps, but never the Compass app. Just hide it.

    - Maybe something about your unlock messed up, you can use Cydia to reinstall the unlock package.

    Personally, I would advise against deleting Cydia and just hide it.

    You're correct. I spent last night reading up on SSH and whether I need to change the password and it sounds like I don't since the only things I've installed after Cydia was Ultrasn0w.

    Just out of curiosity though, it sounds like as long as I'm not logging into random open wifi's, my iPhone should be fairly secure?

    If you get SBSettings you can get a toggle to enable/disable SSH so you dont have to worry about it when connected to a random wifi.

    Thanks for all the explanations! I'm glad someone actually explained how to remove Cydia v.s. trying to convince me not to. Will my phone remain unlocked if I remove Cydia?

    Until you need Cydia again to fix a problem, then you will have to restore and re-JB since you don't have Cydia.

    To add to the chorus against removing Cydia, removing Cydia is like wanting to remove the Settings app because you are convinced you would never want to change any of the iPhone's default settings, and you feel afraid that if you leave it there, an important setting could get accidentally changed. Can you see how idiotic it would be to remove Settings? That's pretty much what Cydia is to jailbroken phones.

    I use Setting's all the time. Changing my default ringtone, adding wifi networks, adding email accounts, etc etc. I only wanted Cydia to use ultrasn0w to unlock my phone so I can use it overseas. And again, I'm thankful for the developers and my unlocked phone.

    (But I've definitely realized how hard it's to get a direct answer on how to remove Cydia amongst the threads/posts.)

    You already got an answer on how to remove Cydia, would have been pointless for me to repeat it. I guess you've also got more than enough warnings about removing Cydia, but thought I'd just give it another go. :p

    The major concern with removing Cydia is that there would be no good way to get it back...

    If a few days down the road GeoHotz makes a frantic tweet about a major vulternabilty and that you need to update to the latest BlackSn0w right away then you'll be SOL unless you restore your whole phone.

    If you just hide Cydia you'll at least be able to access it with Spotlight and update your sn0w install. Best solution, if you just don't want to deal with it, would be to DL Poof and then hide both Cydia and Poof. You will still be able to get back into Poof to unhide things with Spotlight.

    Does Spotlight natively find hidden apps, or do you need to install Spotbright?

    Poor OP, he wants nothing to do with jailbreak, and here we are telling him to install more and more JB stuff... :D

    Now it hides them using LibHide which makes it so you can find them in Spotlight without Spotbright. :D

    Ah, great to hear, didn't know that! Is that also the case with apps in category folders?

    Yup. Since the integration of libhide to the apps this has been a feature.

    $20 says we see a post someday from camoMike that starts with "Help" :eek:

    I can't imagine anyone worrying so much about a single application.

    If he is that worried, he better remove Safari also.
