My best friend and a client of mine have the same name, and it's way too easy to accidentally click on the client when I'm having a more adult or humorous conversation with my buddy at the same time as my client.
Is there a replacement iPhone texting app that uses the native SMS (I have unlimited texting plan so don't want to bother with giving all my contacts a new handle nor requiring them to download an app themselves), but allows a couple other features like choosing what color a contact's talking bubbles will be or choosing the messaging font?
I really don't want to jailbreak if at all possible.
