Iphone activation/contract issues

[eatjello]

Ok, I've searched these forums for a solution. and i cant find anything.

So here's my issue,
I bought a brand new iphone, through a buddy.
I didnt have a sim in the phone, and i connected it to itunes, and it said put a sim in, so i put my sim in so it could activate itself.
I got a popup on the phone saying "succesfuly activated"

On my current contract (non iphone contract) i don't have unlimited data, or texting. i have like 1500 texts and no data.
Someone was saying that i need to have an iphone contract to get unlimited data and texting, and that it is more expensive than a non iphone contract? They also said that i HAVE to extend my contract?

The regular att contract for unlimited data AND texting is 35$ a month.

I was told for the iphone contract its like 30$ for data, and 20$ for texting, then i have to extend my contract yadda yadda.

So is there anyway i can use my regular att contract and use the 35$ unlimited data and texting plan?
Or what are my other alternatives?
Do i need a Gevey unlocking sim?

Thank you so much for the help

You can keep your current plan bro.

ALL you have to do is add the "iphone data plan" which gives you unlimited data and 200 txts. It costs an extra $20 a month (for a 2g) or $30/month (for a 3g).

Thats it....you dont have to extent your contract or change your voice plan.

excellent news. Do i have to go to the att store to do that?
because i can't figure out how to do it online.
and how much is it to get unlimited data and unlimited texting?

Im sure you can just call them and have it added.

The unlimited data w/ 200txts is what I listed in the first post.

I think to have unlimited texting....its like another $15 or so.

I'm glad i don't have to extend my contract or anything

thank you very much cpjr
