What are some apps for iPhone that let you send videos to your phone contact?

Hi. At the moment I don't have phone service, so for the time being I'm using this (almost free) app called Text Plus on my IPhone 3GS.
It's pretty nice. It lets you call, text, sending pictures, but it doesn't let you send or receive videos from your contacts.

So I'm looking for an app that lets me do that. I recently found this app called Video For Kik. Which lets me send people videos vie Kik, but I think my friends have to have Kik also, and plus the video recording is limited to 45-46 seconds. I want more time than that.

So what are some apps that let me send and receive videos to and from my phone contacts? And is there a way that I can send and receive videos on Text Plus?

I really appreciate your help.

I like WhatsApp many people have it, you only have to have their phone number… They will need to have WhatsApp too. WhatsApp is free on all devices except iPhone in which case it is 69p? I think, maybe 99p?
