Hipster (like Path) uploads your address book emails to its servers
I wrote a little MobileSubstrate (Jailbroken iPhone) shim to intercept the most common API used to access this data, block its use, and alert the user when it's happening.https://github.com/bri3d/AddressBookPrivacy/downloadsIt should be available in the BigBoss repository as "Address Book Privacy" sometime tomorrow.My tweak catches and displays the use of address book data as it happens, and based on my observations I think the Hipster version of address book theft is a lot less egregious than the Path one. Hipster accesses your address book only when you ask it to "Find Friends" - "Contacts" is selected by default. While this certainly shouldn't be the case, it's nowhere near as bad as Path, which sends all your contacts without asking every time you log in (along with again if you select "Find Friends").
