One of the moments I felt really stupid was when I finally discovered that I can type in special characters (as in Voilá for exaple) with the virtual keyboard. This was 1,5 years into using the iPhone.
Simply hold your finger on a letter for a second and a little popup with special characters will appear.
Haha, this reminds me of when I found it but I hardly used it ever.
I do like the trick where you can hold your finger to go to letter or number screen and slide to something and have it pop back over to the previous screen after you let go. That sounded confusing.
I love finding new tricks.
Ah, another new discovery for me! Thanks for the tips! :)
