Phone Plans and Hacking E-mails on Phones…?

I previously asked a question about the legality of installing key loggers on ones own desktop with intent to hack into someone else’s e-mail. But now I need to know if someone can hack into someone’s e-mail on their phone via a phone plan. Ever since Thursday afternoon I noticed I couldn’t get into my e-mail on my phone. I realized my dad blocked it off. My phone is a Kin One from Verizon Wireless. I really need to know: Although he can block off my e-mail access on my phone, can he access it himself at the same time? Any useful information at all would be immensely appreciated! Thanks!
