I have contacted Apple, though these problems appear to be roughly concept with iPhone owners upgrading to OS4.  Since my upgrade, EVERYTHING lags. I can sort a total sentence, with zero looming on the screen, 10 seconds after – BAM! – it appears. I can’t even send messages but emanate – simply dire the “send” symbol brings this phone to it’s knees. Yet an additional delay. Receiving a phone call is an strenuous charge (the phone lights up, 2 seconds after it decides to ring and arrangement who is calling). If I cannot perform the simplest of procedures, let alone operate my phone to MAKE A PHONE CALL but an issue, what operate is this expesive device? The map focus is finish obsolete – I have a wait for 30+ seconds after the the app starts for it to even commend inputs.  I can’t even strictly get assistance from any one at Apple but profitable for it, not even a elementary email. Great, thirty dollars to discuss it me how screwed I am – they do not even have an central answer. I have attempted tough resets, bureau restorations, zero is helping. If there is no central repair for this, and I am forced to hillside around third celebration equates to and stay eternally in 3.1.3, cruise me a mislaid customer. If the 3G is unqualified of using rightly with OS4, the choice to ascent never should have been allowed. I goal AT&T will put a little vigour on Apple to yield the millions of iPhone users with a little simblance of patron service.Â
