I know that this is not the right place for hacks requests, but i couldn't add a new topic in the requests section. (i don't know why?)
anyway, could you please consider CallLogPro v5.0-1 for iOS 6.x cracked. as it's a very important tweak for a lot of people. (I bet upgrading from ios 5.0.1 to ios 6.1.2 on your kind upgrade for this tweak).
