You can jailbreak, unlock is tricky. You need to update it to iPad baseband 6.15.00 and use ultrasn0w, but when you update your baseband, you can't restore to a stock IPSW until that IPSW has a baseband version that is greater than or equal to 6.15.00. That meaans if you want to restore or update your iPhone, you need to restore using a custom pwnagetool IPSW.
