Hello, I have iPhone 4s. I am not sure about whether I updated my iphone to iOS 7.0.4 by OTA or iTunes. I cant remember. I have many smartphones that I keep testing for my blog. I made the classic mistake of jailbreaking my device without restoring it via iTunes to make sure I am clean which I should have done cause I dont remember. Fortunately everything is working fine and I was able to download and install few cydia apps on my phone. Now my question is should I just continue using my phone or should I restore via iTunes and jailbreak again the right way ? I read there is a SHSH blobs issue. Or is it simply impossible to jailbreak if you have updated via OTA? Which means I must have updated via iTunes only? Thank you.
