I am going travelling next month and wondered if there is a way that i can install something on my phone that will hack WIFI passwords, so that i can keep in touch whilst i am away,

I have been googling for the past few days and cant seem to get anything that works.

I have tried Wep Gen - that dont seem to work on anything.... Aircrack just seems to crash (prob because i am on os 4.3.3

Ive also read about iwifihack but everyone says its just a scam,

Does anyone have any advice or can point me in the right direction,

Thanks in advance....
