    Seb8 years, 9 months ago

    Hi!I have a huge problem after doing this.The “official” ibooks doesn’t show up in itunes, so I can’t transfer any document.In fact, when I explore my new ipad with ifun box, I can see 2 ibooks. The first one is the “normal”, and the second one is at my ipad’s root (sorry for my english, I’m french). think that the two ibooks are in conflict.Any solution?

    I did everything here. But at the end, when I clicked the new ibooks icon, it just crashed right away. Any ideas? 

      Rafael Ruiz9 years, 2 months ago

      Hey guys, after installing the squared icon, DON’T delete it, syc with iTunes first, load some books, respring, and then you can delete it, it really works, it’s just that this guide it’s not complete. After you delete the rounded icon and respring the new icon will still be squared so go to:  You only have to upload some images through iFile and that’s it. I’m using: Iphone 4 with iOS 5.1 

    smb9 years, 4 months ago

    I tried this twice, and it doesn’t work for my untethered iPhone 3GS. and also, after the rounded icon was deleted and the phone was respringed, the new iBooks icon still looks like a square (in the guide’s screenshot it looks rounded again). =/ please help?

    Owww…. Thank you!!! … Works perfectly here… TYSM

    Misdemeanor019 years, 4 months ago

    Bless you! I followed the steps a bit haphazardly but it worked! iPhone4, 5.1 

    Ernesto9 years, 4 months ago

    I did it and worked fine, except for the app icon, which remains square. I deleted the rounded one first, then respring again, and the icon is still square and looks sooo ugly! Any ideas?

    Rfourb9 years, 4 months ago

    Thank you! This worked great on my untethered old bootrom 3GS 5.1. Don’t forget to set the permissions to 777!
