i have been out of the whole JB and update world for a while now.
i currently have an iphone 4 on ios 6.1 Jailbroken.
i really need to do a restore of some kind (phone is terribly slow), and am wondering if its still possible to restore to 6.1 or 6.1.3 since i heard shsh's dont work anymore.
other options is to upgrade to ios 7 or 8 (in this case i dont mind loosing the JB - mainly needed it on ios 6 for wifi and data quick switches).
so the question is how does the iphone 4 handle ios 7 or 8 vs 6 ?
will appreciate some insight and tips
