Could someone kindly explain what an SMS program does? OK it sends and receives texts, but what else is there to do? Are there any privacy settings? I tried a program that hides texts from up to five numbers, which worked great until one of them sent me an MMS, which appeared in the normal way. Not much privacy there...
I have of course set up a password so nobody can do anything on my phone, but there are occasions when I'd like to let someone (OK my wife!) use it to make a call without worrying about private texts coming through while she has it.
