Note:

You need your SHSH blobs saved in order to downgrade. If your iPhone 4S or iPad 2 have launched Cydia before, Cydia server should have saved the SHSH blobs for you automatically.

Tools you need:

SHSH blobs, either saved on Cydia or computer locally

Click IPSW button and select the firmware (iOS 5.0.1) you want to downgrade. Once you locate iOS 5.0.1, Redsn0w will ask you for the latest firmware iOS 5.1.1.

 

Under Blobs section, click Remote if you have jailbroken your iOS device before because Cydia automatically saved your SHSH blobs. Click Local, if you have saved your SHSH blobs on your computer.
Click Next and let Redsn0w do all the jobs.

How To Add Custom Ringtones On iPhone

 

The choice of ringtones on Apple iPhone are very less. The official way to add your favourite ringtone to iPhone is purchase ringtones via iTunes Store. But the iTunes do not provide music or tones purchasing service in every country. So how are we able to use custom ringtones on iPhone?

Your ringtone file must be .m4r file extension because iPhone reads .m4r as ringtone file. You can find .m4r ringtone from many sources. Example: Zedge, there are tons of free iPhone ringtones for download.


Look for a ringtone you like on Zedge and click Import to iTunes button to download which is in .m4r format.
Open iTunes, click Edit and then Preferences.

 

Tick Tones box and click OK.

 

Back to iTunes main screen, the new Tones options will appear under Library. Drag and drop your .m4r ringtone into Tones folder.

 

Plug in/connect your iPhone, select Tones tab and tick Sync Tones box. Click Apply to start syncing.

 

When it is done, the new ringtone is already stored on your iPhone (Settings > Sounds > Ringtone).
