BUYING- Guitar Hero/Guitar (PS3); iPhone running on Virgin Mobile USA

I can never find either of these in any store around me, i looked in every store within an hour of my house :/ I'm looking for any Guitar Hero game on ps3, or more specifically the guitar controller (Guitar Hero 3 is preferred )
I am also looking for an iPhone running on Virgin Mobile USA. Cannot find this in stores either. I trust the sythe community way more than eBay or Amazon, so I thought I'd check here first let me know what you have, can pay with paypal. A middleman should be used, although I'm not sure how a non-virtual sale would use mm, inform me?
thanks, from zackcrackpack
