yes the call detail comes up and there are three option to choose open contact card , call no. Delete.(i did not check whether they are working or not ) and when i press back botton it stops responding(or it freez,or stuck here ) nothing i can do there and later like every app give option when stuck "blah blah application is not responding close now?yes or no...

And good news is that it happaned two times with me.and from third time when i try it back botton was working properly.
perhaps it was happaning only me (i was in a hurry and did not let it load properly)cheers
