I suggest everyone tries this app!
I'm all about customizing my phone with random little apps. This one I found last night is called "Hello", and it is a very simple yet extremely elegant sms app. Everything is sorted in to tabs, and the coolest feature I've found so far is when you click on a picture that was sent to you through texts, it pulls up all the other pictures in that particular thread so you can quickly save them all instead of doing it one by one.
Just thought I would let you guys in on this little gem I found! Hope you guys give it shot!
