The lack of Messages app alternatives on Cydia could be either due to the fact that biteSMS and others have pretty much covered all bases and are extremely functional, or it could have something to do with the amount of work involved in creating such an app. Whatever the reason, the guys over at Handcent haven't been deterred and have released their HandcentSMS app through the Cydia store which they believe can unlock the messaging potential of a user’s iPhone. HandcentSMS is an entirely free, very powerful and highly customizable alternative to Apple's native app which handles both SMS and MMS messaging services.
