On Android, you can easily install a replacement for the default SMS app. iOS users, on the other hand, have to jailbreak their devices to be able to do that. Once they do, they can download BiteSMS - an amazing messaging app that is has just gained compatibility with iOS 7.
BiteSMS is not new. Actually, it has been available in the Cydia Store for quite a long time and due to a wide array of features it offers, many find it the best tweak for jailbroken iPhones. However, the app has recently received an important update that has made it better than ever, as it now supports latest version of Apple's mobile operating system as well as a redesigned user interface and plenty of bugfixes.
After the update BiteSMS looks a lot like the default SMS app, which is a good thing, because users can make a smooth transition to BiteSMS and benefit from its unique features. Those include quick reply window, signatures, contact pictures, improved security settings, and more.
If you're using a jailbroken iPhone, head over to the Cydia Store now to download the update for BiteSMS. Keep in mind, though, that it will display banners ads unless your purchase a licence. By doing so you will support the maker and future development of the app, so it is a worthwhile investment.
