Ok so coming from android I did not have to deal with new os version not being signed. Having just read the post recommending to update to 7.0.4 made me want to backup my evasi0n7 jail broken 5s in case I brick my phone as this happened quite often with android at least. Now, when I back up through iTunes is it necessary to update app data as well, because without app data the whole backup is only 120mb and I dont understand how that would help a bricked phone? I do not care about tweaks, I just simply want to restore to a fresh phone with only the jailbreak and cydia installed. Also, are there any recommended 3rd party backups apps? In the past I had trouble restoring from iTunes and often got errors.
