I was going to recommend bitesms but it's tough to convince people that they need anything more than a quick reply option. I was stubborn at first and I bought irealquicksms because I decided I didn't need the full-blown irealsms program. When they stopped development on irealquicksms and they upgraded me to irealsms for free, I was still stubborn and kept using the stock sms app (only used irealsms for the quick reply/quick compose functions). When I finally decided to try the full irealsms program, I couldn't believe what I was missing.
Then I got my iphone 4 and really missed irealsms. When I was finally able to jb, irealsms was a bit buggy so I tried bitesms. Bitesms is even better than irealsms and it's cheaper! There are a couple features that it lacks but they are constantly updating the app and those features will be added shortly. Plus you can use it for free if you don't mind looking at ads (I hate ads though so I just bought my license since my trial expired today). Well worth the $8.99.
What are the other things that BITE SMS does that quickreply and other programs don't... because i can't really imagine what more i would need... is it just like customize colors and stuff like that??? quick reply has worked great for me... i gotta wonder what bitesms offers that is worth 8.99 for?
