Since the early days of the iPhone OS, arabic wasn’t supported on the iPhone.
The letters used to either came up garbaged or in reverse and separated!
Luckily there was Arabtaller to introduce the Arabic font and support to the iPhone via a third part install; nevertheless it was a commercial package and the user had to pay up to $30 for a single license, even that and the product wasn’t a complete solution.
Finally in iPhone OS 3.0 apple introduced the Arabic language and we are all glad it did.. Websites now display Arabic font properly but there is something wrong with the keyboard.
Many letters are missing (Check out the attached picture). What i directly notice is the absence of the letters (ء) and (ى).
Apple if you are reading this, consider adding the shift key for the additional keys found on any standard keyboard!
