A few weeks ago we present you a tweak which will tell you whether an SMS message sent from your iPhone has reached the recipient or not. That tweak was available in beta version but it works quite well, but yesterday another new one called SMSConfirmation appeared in Cydia which basically does the same thing. By installing SMSConfirmation you will be warned when an SMS message sent by you reaches the recipient or not, the tweak being designed in such a way as to announce both the successful sending of the message and the impossibility of sending the message.
SMSConfirmation is available for free in Cydia in the ModMyi repo. The tweak is compatible with iOS 5, but it brings a functionality that Apple should have implemented since iOS 1, but which we probably won't have available soon without a jailbreak.
