this is not a hint or tip but hopefully it will be after someone comes up with the answer. before i update to ICS i could unlock phone by swipping then i had to enter a pin!! now all i need to to is swipe but i would like to enable the pin again but cant find out where i do it? can anyone help please?
Maybe this is a tip, or maybe someone won't see it as a tip, but it is certainly helpful - when you update your android to ics, but you haven't rooted your phone to do so, be sure to factory reset the phone after updating, since there is a big possibility that you will have problems with your phone auto rebooting, or media not refreshing after upload.
