iPhone 3G signal always drops out on my phone to the extent of me wanting to throw it at a brick wall!! It's the worst signal ever, Iv heard that the iPhone 3G was fitted with a dodgy antenna which is shielded behind a metal cover which also helps destabilize local signal it makes me sick and very frustrated daily to know that apple released it in that condition and say that they're not responsible for the signal...
Technology, we can't live it..but, we can't live without it!
Peace
