How about more information...
Define what you mean by, "Crashing."It freezes up as soon as I click an application. Also it will re-spring and will go on a safe mode with a message saying one of the apps has failed bla bla bla and now its doing a safe mode bla bla bla
Does it crash to the springboard? Yes it does.
Does it reboot the phone? It doesn't reboot instead it does a soft re-spring
Does the screen freeze? It does a soft re-spring after the frozen state.
Does it get stuck on the Apple logo? Sort of... I did noticed yesterday that when I click the call app, it takes me to the call menu screen and when I click recent calls or contacts, it doesnt do anything so I did a hard reset but was stucked in the apple logo. Waited for 20 mins but was still stucked so I restored the phone thru Itunes again, use Quickpwn, jailbroke and unlocked it again. Now it's freezing up again.
Also, is it consistent, or is it random?
