Need help w/a 2G

[StaticCat]

I've downloaded the SwirlyMMS for the iPhone 2g and I can't get any of it to work. I've done almost everything that people have suggested although I am not that computer literate so I need things explained rather slowly to make the point and simple - that helps.

I was wondering if anyone could help me with a step by step way to get the SwirlyMMS working on a 2G without having to contact AT&T and removing anything - I don't know how to do that either ( like I said not techy )

I would appreciate any and all assistance this way I can see if this is something I want to buy, I only have 12 days left on the trial so as soon as possible would be appreciative.

Thank you in advance,
Cat
