I'm near the end of the game but I have never recieved a letter from Sara. I've gotten all the letters from everyone else but she doesn't want to write to me. I would like to finish this sidequest and get the ultimate weapon. I've already been able to get to legendary blacksmith, secret ??? dungeon, except I can't get sara to write a letter to complete that and ultimate weapon. wtf. The ds version just lets me write letters to activate it but for iPhone, non avail.
Well, I don't think it's possible to send any messages in this version Uhm.. if you switch to Refia you will get messages from Takka and if you switch to Arc you will get messages from prince Alus I think..
I was having same problem, so I tried going through crystal tower all the way up to portal to fight Xande. I teleported out and there the letter was... I had beaten all dungeons and opened 96% of chests. Make sure to talk with all party members to mog, u should all the remaining letters
