Iphone (problems after jailbreaking)?

So I jailbroken my phone add any time i try to type something in, in a app that app messes up and I go back to the home screen but I can type in safari and any app I have in my iphone. I just jailbroken my phone and whenever I put my phone in safe mode none off my apps cancel out what should I do?!

It would really help a lot if you mentioned which iphone you have and what app was crashing.
