As a side note, you can do something similar (albeit a thousand times safer, as you (= your computer) issues the certificates, not some unknown hacker) to fool Game Center.

I get maybe 20 Game Center invites from 8 year old kids on a daily basis... The reason is I faked my score on the popular game Jetpack Joyride (I'm #1 out of 16 million players), and also beat Minesweeper's hard map in a few milliseconds (second guy is I think over a minute)...

I did it just for fun and experiment, but apparently there are kids who really take Game Center seriously and I stopped doing it, not wanting to hurt their feelings. The instructions are here: http://corte.si/posts/code/mitmproxy/tute-gamecenter/index.h... , but please don't go crazy, and don't submit ridiculous scores like I did. You may get your account banned (which is not a great thing, if you're a developer).
