My girlfriends brother is using an Android phone and he is somehow able to call people from his phone and make someone elses number appear in the CID instead of his. Is there currently an app or jailbreak tweak that will allow me to do the same?

SpoofCard works

Thank you it worked great. It's probably the same thing he is using.

Also callerID Faker is on cydia.

Spoof gangster it's in the app store. No jailbreak required.

So, I assume it goes without saying this will not work for texting and it won't change what shows up on the billing record.
