You more_2 are a Tzadik Gomur for having recited thy prayers, and B’H you repeated nothing when you got your tuxedo on, because this would have been a violation of the 3rd of the 10 commandments Chas v’Sholom.
As far as I-Phone, B’H for this technology; At least if you enter a restroom with I-phone in your pocket, no Halachic issues. If enter restroom with conventional Siddur in your pocket, Halachic issues arise.
Because of Tzadikim like you who know how to put this wonderful technology to good use, I am not wasting my time at this anti-computer gathering in Flushing on Yom Yerusholayim. Even more so, because I know couples who met on Frum dating sights & are happily married.
