I decided to clone Tumblr because I have two very different Tumblr accounts. Tumblr’s built in secondary account feature does not give enough options for both of my accounts. I also prefer Tumblr’s iOS app over any other 3rd party Tumblr app. This process will also not work on a lot of other apps. I made this guide only with Tumblr in mind. All applications used in this guide are free.

Although cloning Tumblr is not dangerous, I am not responsible for any damage done to your device if anything should happen.

Prerequisites

1. Jailbreak your iPhone/iPod using Evasi0n. http://www.evasi0n.com

2. Download iFunbox (this will be used to install the app, nothing more) - http://www.i-funbox.com/

3. On your iPhone/iPod use Cydia to install iFile (use the trial)

4. On your iPhone/iPod use Cydia to install AppSync

4a. You will need to add a repo to Cydia to install this

4b. In Cydia, click on Manage, then Sources, then click Edit, then click Add

4c. The repo I used is http://cydia.myrepospace.com/declanland/

4d. You can get the iOS6 AppSync from other repos as well.







Before we begin, you should take note that the two aspects of iFile we are going to use are Edit and Copy/Paste. I have provided images to show where these options are located.







1.Edit







2. Copy/Paste (which is in the Edit menu)







After you have completed the prerequisites open iFile and Navigate to /var/mobile/Applications/Tumblr







Click Edit and copy Tumblr.app and iTunesArtwork. If you don’t know how to move and copy files very well, I suggest copying the Tumblr.app folder and the iTunesArtWork file separately so you won’t get confused.







We are going to need to paste these files in a new location.Find a place to make a folder. I chose /var/mobile/documents







To make a folder, click Edit and the click the Plus button on the bottom left







Name the folder Payload







Paste the iTunesArtwork outside of the Paylod folder.







Go into Payload folder and then paste the Tumblr.app folder.







Go into the Tumblr.app folder and find the file named info.plist (its a ways down)







Click it and chose Property List Viewer







We are going to be editing two values here. CFBundleDisplayName and CFBundleIdentifer. I have marked them here.







Click CFBundleDisplayName and change it to whatever you want your Tumblr clone to be called (pay no attention to my emojis)







Click done. Next click CFBundleIdentifier and change it to “com.tumblr.xxx” where xxx is the name you chose for CFBundleDisplayName







Click Done and then Done again. Go back to /var/mobile/documents or whereever you chose to put your files Click edit Select the Payload folder and the iTunesArtwork file and then click the compression icon/zip icon







Name the zip whatever you want.







After the zip has been made click the blue > next to the zip







Change the name of the zip to xxx.ipa where xxx is the name of the zip







Click Done Click Edit if you aren’t in Edit mode Click the zip you just made into an ipa Click the mail icon and mail it to yourself (or if you know how to move this file to your computer, do that)







I suggest deleting all items (payload folder, zip/ipa, and iTunesArtwork) just to make sure nothing messes up.







Once the ipa is on your computer, plug your iPhone/iPod into the computer and open iFunbox. Make sure it connects to your iPhone/iPod Click on the Manage App Data tab Click Install App Navigate to your ipa and install







Done!

If/when Tumblr updates, you will need to delete you old clone and make a new one.
