MyPhoneData.com - might be useful for others

Just in case people want to have a little look through all the deleted messages etc, if H or P backs up their iphone regularly as mine did, it's their undoing, nothing is ever deleted for the bargain price of 10 quid.

Alternatively.... if you know you're living with a liar, save yourself a tenner and kick the cheat out. Let them protest their innocence rather than lowering yourself to their level....

Lol also true

But it might be useful for those suspecting but unsure.

How on earth did you download something for his phone??

I'm not planning to use it, however. Gave up checking!

He needs to back his phone up which a perfectly reasonable thing for you to suggest he ought to do and then once that's done, every text, telephone call, email, voice message is on your desk top.
It's all very well saying throw em out but I think sometimes you do need to see something concrete, I did anyway.
