Every time in download bite SMS and then go into it, it's still just the stock messenger. It says bitesms but it isn't it. Please help, I've looked all over for help! I have an iPhone 4
BiteSMS has been discontinued since the release of ios8.
However due to popular demand that it be resurrected, mootjeuh over on reddit has decided to work on a tweak to replicate most of the features. It's currently in beta so you will just have to wait.
it looks like the stock messaging app for the most part. if you slide down in the convo page, there'll be a search bar and a settings button next to it
