Is using they and their as gender independent terms acceptable to us on Fluther?

Ex 1: The flutherite went to buy an iPhone. But they were stymied in the process when Apple’s activation servers went off-line. For the moment, their iPhone is bricked.

Or would you prefer both genders slashed together:

Ex 2: The flutherite went to buy an iPhone. But he/she was stymied in the process when Apple’s activation servers went off-line. For the moment, his/her iPhone is bricked.

Or pick a single pronoun, either masculine or feminine, at random:

Ex 3: The flutherite went to buy an iPhone. But she was stymied in the process when Apple’s activation servers went off-line. For the moment, her iPhone is bricked.
