Free Texting Apps that don't need Wi-Fi?

I'm going out of the country for a couple weeks in March. I have an iPhone 4 so I know about iMessage. However, where I'm going, Wi-Fi access won't be easy to find/will be expensive. Is there a texting app that allows me to text to other iPhones without Wi-Fi access?

If I take the sim card out would the owner be able to track the iphone?

Okay so I found this iPhone 4/4s and I gave it to the people in the mall they gave it back to me because the owner didn't claim it in 2 months. The phone still has service and it's working correctly. What would happen if the owner started to track the iPhone and traced it back to me. Is there a way for them to trace it back to me? Even tho I took out the sim card?

How to make my website (a social networking site) into a iPhone app?

Hi, I'm trying to make my social networking site invocanada.com into a mobile app, not a webapp I want it to be native and am wondering if there's anything that will make me a template that will refresh itself with the information in the background. Anyone with any info please let me know!
:)

Added (1). If the native app is too difficult is there a way to make a web app that looks like a native app? The only reason being is that every web app I have used it tends to be blurry and not clear, and VERY SLOW and I don't want that. I don't have a mobile website either which I know you need for a web app (obviously) Is there any open source programs that would allow me to do all of this? The whole goal of the project is to stay under fifty dollars so Ya any suggestions would be gr8!
