I purchased an iPhone 4 off eBay that came with 6.0.1. I ran TinyUmbrella which found and saved the SHSH blobs for 5.0.1. 1) Does that mean that I can downgrade to 5.0.1? 2) Is 5.0.1 a firmware that's stable and works with the new Cydia? 3) If no, can I then upgrade it then to 5.1.1 with no blobs for 5.1.1? 4) Or, should I just stay at 5.0.1 when I get there or stay at 6.0.1 and wait on untethered option? The reason I need the jailbreak is the lock options available for folders and programs before giving this iPhone to my teenager. Thanks!
