hi, does anybody know a good application to use preferably using the internet on a blackberry to get an unlimited international texting or perhaps one that has a flat rate fee? thanks!

There is an application called cellity that may do what you want, go to cellity.com and have a look.
I am not 100% sure but I think the person you are texting has to have the software on their phone too.
Worth a look maybe.

Best thing is if the other person has a BB as well. PIN messaging is included in your data plan, regardless of whether it's international or not.
