How do I trick my girlfriend into letting me snoop through her phone?

Just ask her if you can see her phone. Then if she says no then wait to she asleep.

take it and say maybe to look for it at her friends house,when she leaves go for it.you know shes a tramp.get the proof.

Are there any special tactics or tricks i can use to get her phone away from her? please none of that.. "you shouldnt look through her phone." i just want advice on how to get it. not anything telling me not to. thanks
ohhh yeah... it's because she wanted to go to a psychic last night so we went... lol... and the psychic told me not to trust her.
