I had my IP5 jailbroken on 6.1.1, noticed that the apps kept on crashing when I would first open them up, did a full restore and updated to 6.1.2 last night, now I am considering whether I should JB my phone again or just leave as is. I have also noticed that some of my apps keep timing out on update so I am getting quite annoyed with this.
The only reason I had my IP5 jailbroken was to use the color keyboard which I am very fond of, now I don't have it and don't want to JB my phone again just because of a fancy keyboard which for some reason I cannot find any app on normal appstore that will do this.
I was experiencing the same crashing issues....I updated to 6.1.2 last night and
jailbroke with the latest evasiOn 1.5.1...everything is working smooth now
