I'm having serious issues with Cydia. I keep getting errors like "the following signatures were invalid" or I get some "size mismatch" error. I dunno what's causing this problems but I'm guessing my verision of ios is too outdated.

So since I'm on 4.2.6 and never upgraded since I got my iPhone is it too late for me to upgrade to another version and jailbreak again?

I'm having a bunch of other issues too like my phone keeps crashing and just becomes totally unresponsive, I think I just really need a format and fresh install.

if you don't have shsh blobs saved either cydia or tinyumbrella you would have to go to the latest signed firmware, I think it's 4.2.8 for Verizon it would be a tethered JB. it's really not as big as a deal as people make it out to be.
