The methods to /save/ your SHSH will no longer work for 4.2.8 because it is no longer being signed. The Cydia "make my life easier" button will only work for currently signed firmware as well. Your only option is to /dump/ the SHSH with iFaith. It is a PC application only. You just open it up and click "dump SHSH" then it will walk you through putting your phone into DFU mode and then it will exploit your phone with limera1n and dump your SHSH file from various boot logos and lockscreen images.
The act of dumping poses absolutely no risk to your phone. When it is done it will ask you to save it to your hard drive(place it somewhere easy to remember). It will also ask you if you want to e-mail it to yourself(I would advise doing this, the more backups the better).
In the future if your firmware becomes corrupt and you need to restore 4.2.8 you will need to run iFaith again and then build a firmware with the SHSH you saved.
