Australian in USA in need of BYO pre paid plan.

Hello there,

I'm an Aussie currently studying in Oregon, and I'm in need of a provider. I've got an iPhone from home, but because I'm only here for 6 months, I don't want to sign up for a contract. What's my best hopes for getting a prepaid plan with data (2GB is fine as I'm used to restrictions back home)?

Thanks in advance
