You know how you can type the "greater than" sign and then the #3 on face book and a heart will post but from my cell phone it does not work. Does this make sense?
Ah yes, got ya. unfortunately i believe symbols/numbers do not convert with the app. i think you have to be on the mobile site. same for tagging someone, but not 100% sure. i have a sign in my name on fb and it will not show up on my phone, it just appears as a box.
you type the ♥ symbol by clicking the ?123 button to go into number mode on keyboard, then hit alt key, then longpress on the bullet • and the playing card suit images come up. Slide over to ♥ and viola!
