iphone on orange

I am looking to get a PAYG iphoneon orange. Just phoned their sales team to ask if there is a bundle or a payment i can make each month for unlimited internet, They diddnt know lol.

I had a PAYG iphone on 02 and got unlimited internet for the 1st year and then ould pay so much a month after that.

Does anyone know if there is some kind of package with orange?

Thanks
