I have Lockdown installed on my Iphone 3GS 3.1. It works on 3GS only if you are not browsing safari. i have my SMS and email locked but still can read an incoming SMS or Email without password prompt if I am on Safari. Anyone could resolve that issue?
I think that just happens if it ever pops up where all you do is click reply rather than having the phone locked, but I don't know how to fix it..sorry
actually it happens whenever the phone is not locked so the app doesn't help if you just want to lock sms while your friend (or girlfriend ) browses on safari or is looking at pictures.
