Safari performance on iPhone 3G?

It loads up bIng and other pages, but google, Facebook, twitter, and myspace runs so slow it crashes. Any fixes please?

Hmm I thought all iPhones came with 4g service, maybe that depends on the carrier not the phone itself. You can upgrade your phone, I don't promise that it will make your connection any better if you still have 3g service, but it might cause it may be your phone, has the service always been that slow? If so it probably isn't the phone. If you want to use this service a lot and is important to you you might see if either a. Your present carrier has 4g service ( I know iPhone is compatible with it, although I'm not sure which iPhone you have, I have the 4s, if they don't or you can't get it for your phone (if your iPhone is maybe too outdated to get 4g?) and like I said, if this important to you might consider switching phone carriers. Best of luck.
