The back of my Iphone 5S gold says that the model number is A1429. However, this model number was only available for the iphone 5. I'm very confused as to why this completely original device displays the model number for an Iphone 5 and reads as an Iphone 5 when connected to itunes.
iPhone 5s, iOS 8.0.2
Then if everything points towards this phone being an iPhone 5 and it connects to iTunes and shows as an iPhone 5, then it is very likely that the phone you have is an iPhone 5 and not a 5s.
Where did you buy the phone? If you had purchased directly from Apple then you would get an iPhone 5s. You could have been scammed if the phone came from a re-seller.
If you purchased in the Middle East, then they sell grey market imports there, so it is more than likely that they passed off what was an iPhone 5 as a 5s instead,
Please give us more information about where you purchased the phone - if you purchased from a legitimate source, this would not have happened.
