If you cant turn off via the icloud menu under settings mneu & youve tried all the resets/suggestions on here then you have no choice but to wipe your phone to factory settings via recovery mode & do as below.
Make sure your phone is synced upto date to your options & apps all tally up with itunes & your phone.
Make sure you iphone is backed up to icloud (as couldnt restore via computer that i could find) & your libary etc is fully up to date so when you re-sync you dont loose any of your items.
Download the latest IOS in the usual way ONLY BUT DONT install
Then plug into the usb end into your computer BUT NOT PLUG INTO THE CHARGER PORT
Turn off you iphone int the usual way
Hold down the home button & KEEP HOLDING whilst plugging in charger end
Wait untill the itunes, globe & charger pic is displayed
After a few secs your computer should show a message that your iphone has been dectected in recovery mode
Ok this message & ok erase & update next message
Let itunes do the erase
Once done & phone is wiped DONT TOUCH OR CLICK ANYTHING ELSE ON ITUNES & DO THE FOLLOWING ON YOUR IPHONE NOT ITUNES
Unlock & follow intsructions
Chose set up as a new phone ONLY & set upicloud/itiunes -log in with your passwords when prombted
Once phone goes bck to home screen go to settings, icloud,go down to find my iphone & flick to off. Enter password when prombted & should turn of with a conformation tick
Go bck to itunes & should b displayed congratulations you phone has been erased or something to that effect
Ok that & should b a option to set up as a new phone or restore
Restore from your icloud bck up (this was where im not sure if theres an option to do from computer bck up or not, I just did as icloud but there may b a way round it)
Let itunes do the restore
Wait for itunes to go bck to the orig iphone connected screen
Got to your phone & set up icloud/itunes with your account etc as per steps your phone displays. This should re-set up your imessage, face time & find your iphone as a new setup/new user etc. Keep following until you get bck to your home screen with no messages.
Go to settings, icloud, find my iphone & your should now b able to turn off as per your should b4 wiping - hurrah 😉
Job Done!!
Now to restore-sync- put all your stuff bck on 😉
B4 syncying make sure the sync options are clicked for your prefrences - if youve done correctly b4 starting this process you shouldnt have to do this step!! 😉
Sync & re-install all your stuff & let itunes do it stuff
Now its up to you if you turn find your iphone bck on via the settings/icloud option. If you do see below
Give it a few mins for your iphone to go bck onto the icloud server (this is where i swore at it as thought id wasted my time & not sure exac what happened here but on intial try it wouldnt let me do/same message prior to wipe but then second attempt it suddenly worked!! I had also loaded the app as well so you may have to do that also!! this was my stetchy step by step section!!! 😉 If doesnt work keep trying & should work as it should. Do as phone asks/enter password if prombted.
Now your done & all should b all working as it should & all your stuff bck where it belongs
This process is the only way if youve tried all the other options as detailed on other threads on here

Thanks apple for making us have to ponse around doing this cause your software updates mess our phones up
I also learnt my probs where casue i updated my phone via the software update via my phones settings but had no probs with updating my phone via intunes on my computer downloading it. Especially ios7.02 as may my probs worse doing via my phone via itunes not probs at all.
Hope this helps people that have experinced this find my iphone prob & the imeesage/facetime waiting for activation as these were the probs i had & now fixed doing the above.
