Another missing feature in the iPhone messaging application is the sms delivery reports!
These can be quite useful, so follow the steps to get them into your iPhone!
Launch Cydia and add a new source “http://iphonedelivery.advinux.com/cydia” without the quotes.
Install iPhoneDelivery (search for it in Cydia)
Go into Settings -> Messages and activate ‘Delivery report’
And now you have the delivery report option on your iPhone 🙂
USE IT WISELY :p
