    Thanks for your help with this..

    If you continue using blacksn0w (not rc2) you will eventually get bootloop again.
    Am I using it now without knowing it (in other words I haven't successfully updated it to RC2) and do I have to find a way to delete it?
    Or will I be using it if i try a sim from a different provider...

    Either way step 6 on the sticky needs updating with this new info..

    I'm a bit wary to try any unlock now...will research ultrasnow...

    Ultrasn0w has always been safe. The devteam looked at and discarded the hole that blacksn0w used - partly because they believed that it couldn't be safely exploited.

    If you have specifically uninstalled blacksn0w or restored your iOS since your bootlop then you are OK. Otherwise you are still running it. Regardless of which SIM card you have in your phone.

    To go to RC2, you need to uninstall blacksn0w and then install RC2 from the correct cydia repo.

    I've done several google searches and It's not possible to uninstall blacksn0w (unless you know of a way) and also RC2 is no longer available on cydia.

    I've restarted my phone several times since fixing the issue using method 2..is it safe to just ultrasn0w it now since there's no way to uninstall blacksn0w?

    If you have a small understanding of the way blacksn0w is loaded, then Mostly iPhone hacking: Fixing Blacksn0w on 3.1.3 gives you all the clues you need to work out how to uninstall it.

    Wow, Thanks for that and I have a newfound respect for you guys that can actually understand pages like that!

    I will keep reading it over and over and do some further research to understand how blackrain works in the hope that I can learn how to uninstall it...

    I did notice that the page say (in big red writing 14 lines down from the top):
    3.1.3 with 5.11.07 BB ONLY

    the red writing is scary as I have 3.1.2 with that baseband not 3.1.3.

    also it shows the tools that I will need are:
    Tools:
    gdb, IDA 5.5, ldid, hex editor (XVI32)

    would you be able to point me in the right direction as to what to use?

    I also typed pushfix.info into my browser and found that the pushfix tool might uninstall it or maybe that's just wishful thiniking...

    any further help/clues would really be be appreciated...

    UPDATE: pushfix 2.0 doesn't uninstall blacksnow, instead they (pushfix.info) recommend searching for blacksnow rc2 on cydia (but the search returns 0 results, even if you add cydia.pushfix.info to your sources)

    Question

    I just re-read the sticky on this thread and found this:

    IF YOU HAVE NO WIFI AFTER COMPLETING FIX 2:
    1) Uninstall blacksn0w (either remove the package from Cydia, or remove /usr/lib/blacksn0w.dylib and re-add the original com.apple.CommCenter.plist)
    2) Reboot your phone.
    3) You should now have WiFi back.
    4) Add the Blacksn0w repository (cydia.pushfix.info) and install Blacksn0w RC2
    5) Reboot your phone

    QUESTION: If I complete steps 1 & 2 (not able to uninstall blacksn0w through cydia as I installed it through blackra1n) will all my (iphone) problems be over?

    I can remove the dylib file by using iphone explorer and i have 2 p.list files (com.apple.CommCenter.plist and com.apple.CommCenter.plist.backup).

    I used plist editor for windows and the files look like this:
    com.apple.CommCenter.plist:
    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
    	<key>EnvironmentVariables</key>
    	<dict>
    		<key>DYLD_INSERT_LIBRARIES</key>
    		<string>/usr/lib/blacksn0w.dylib:/Library/MobileSubstrate/MobileSubstrate.dylib</string>
    	</dict>
    	<key>HopefullyExitsFirst</key>
    	<true/>
    	<key>Label</key>
    	<string>com.apple.CommCenter</string>
    	<key>MachServices</key>
    	<dict>
    		<key>com.apple.commcenter</key>
    		<dict>
    			<key>ResetAtClose</key>
    			<true/>
    		</dict>
    	</dict>
    	<key>OnDemand</key>
    	<false/>
    	<key>ProgramArguments</key>
    	<array>
    		<string>/System/Library/PrivateFrameworks/CoreTelephony.framework/Support/CommCenter</string>
    	</array>
    	<key>ServiceIPC</key>
    	<false/>
    </dict>
    </plist>
    and the backup file looks like this:
    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
    	<key>HopefullyExitsFirst</key>
    	<true/>
    	<key>Label</key>
    	<string>com.apple.CommCenter</string>
    	<key>MachServices</key>
    	<dict>
    		<key>com.apple.commcenter</key>
    		<dict>
    			<key>ResetAtClose</key>
    			<true/>
    		</dict>
    	</dict>
    	<key>OnDemand</key>
    	<false/>
    	<key>ProgramArguments</key>
    	<array>
    		<string>/System/Library/PrivateFrameworks/CoreTelephony.framework/Support/CommCenter</string>
    	</array>
    	<key>ServiceIPC</key>
    	<false/>
    </dict>
    </plist>

    The backup file has no blacksn0w entry so restoring that will disbale blacksn0w. Then you can safely delete the dylib after a restart.

    Another way (without requiring restart) - this is untested but should work fine.

    Install Erica's Utilities and SSH from Cydia (or MobileTerminal or iSSH connecting to 127.0.0.1)

    is:

    Code:
    plutil -EnvironmentVariables -rmkey DYLD_INSERT_LIBRARIES /System/Library/LaunchDaemons/com.apple.CommCenter.plist
    launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist && launchctl load /System/Library/LaunchDaemons/com.apple.CommCenter.plist
    rm /usr/lib/blacksn0w.dylib

    Could be a problem with hacktivation. I can't recall if you jailbroke with blackra1n or something else.

    If you jailbroke with blackra1n you might need to remove it's hacktivation and replace it with a patched lockdownd.

    http://www.hackint0sh.org/f220/130992.htm
    explains how to remove blackra1n hacktivation...
    However that guide is written assuming you can activate legitimately.

    For your needs, it should be adapted... This is my best guess (I don't really have the ability to test this)

    plutil -EnvironmentVariables -rmkey DYLD_INSERT_LIBRARIES /System/Library/LaunchDaemons/com.apple.mobile.lockdown.plist
    Install hacktivation fix from cydia.pushfix.info
    launchctl unload /System/Library/LaunchDaemons/com.apple.mobile.lockdown.plist && launchctl load /System/Library/LaunchDaemons/com.apple.mobile.lockdown.plist


    If that does not work.. try these two steps.

    rm -r /var/root/Library/Lockdown
    launchctl unload /System/Library/LaunchDaemons/com.apple.mobile.lockdown.plist && launchctl load /System/Library/LaunchDaemons/com.apple.mobile.lockdown.plist
