First, download your .pxl file. I'll use iSaber v0.01 as an example here. You can get the iSaber .pxl at http://pxl.ibrickr.com/iSaber-0.01.pxl So now you have your .pxl file. First, rename "iSaber-0.01.pxl" to "iSaber-0.01.zip". Extracting the archive will give you the "iSaber-0.01" folder. Inside this folder there is another folder called "app". Rename this folder to "iSaber.app". And you have your app. You can transfer it normally by SFTP to your applications folder on your iPhone/iPoT and it should work. FAQ Q: There's a "PxlPkg.plist" file inside my iSaber-0.01 folder. What's that for? A: To tell you the truth, I have no idea myself. I assume by the name it had something to do with the .pxl file. In any case, it doesn't affect our app, so don't worry about it.
