I jailbroke my iphone like a month ago and it was sweet but one day i clicked on the phone button and it went to the keyboard and just exited and kept doing this. I checked on the memory freeing app in the app store and it said mobilePhone wasnt running anymore so i think thats why

i rejailbroke my iphone and it fixed it but i wanted to know if theres an easier way to fix it if it happens again
