IPhone message shows as Handcent SMS?

So I unlocked my iPhone 5 and downloaded Handcent SMS and then I reset my iPhone and now when I receive a text instead of saying "message or iMessage" it says Handcent SMS and it also doesn't let me send iMessages to other apple products. Any help?

Sounds like your unlocking failed. I would try a different service if I was use. I used iphonunlocker.com for my iPhone 5, and worked like a charm.
