Can't get into phone menu when on a call

[NWI73]

Since jailbreaking my iPhone 4 running 4.2.1, if I make a call and want to put it on speakerphone for example, when I take it away from my face, the lock screen is showing but when I slide to unlock, it hangs up the phone. The only way I can get into the SB is if I make a call with my bluetooth and the phone never gets a chance to lock. Am I missing something obvious here?

You wouldn't happen to have PhoneCloser installed on your phone would you?

Yes I do and I just un installed it. Good catch - that fixed it.
