ladies and gentlemen i have your answer here
this video i made is way better.no pc tethering no cables just strait hotspot connect to iphone 4 and use 3g and details in my description no jailbreak required tried and true. to any1 who thinks the data would be outragous is just wrong. i have a 12gb a month plan and it doesnt even get near 3 or 4 gbs for the month playing regulary. lag wise seems nil works perfect for me and im quite literaly in the middle of the outback of australia on a mine site with one tower five kms away exact. now i have it working and the ps3 just connects no problem now ill be doing another video acctually demonstrating it with a friends ps3 and iphone that has the same problem at work this friday or saterday so check back next week for that. as far as i can find no one has done this on youtube without jailbreaking their iphone which i just refuse to do
This is a pretty old thread, but i thought it might help anyway. If you are just looking to play media with an iphone or ipod touch without jailbreaking, just download sync:stream from the itunes store. start it up, and your ipod with show right up on the playstaition with no hassle.
