There are plenty of phones that provide that, maybe you should check them out.
Unfortunately, a perfectly functioning iPhone 4 is not a right.
I can't tell if your kidding or not. I demand every right since I gave them my dollars for something not working as they advertised it.
But what your LOGIC fails to understand is that none of those phones what I expect the iPhone to do in addtion to making calls (and holding the signal for those calls).
I at least expect the PHONE portion of the device to work PERFECTLY. Especially since cell phones have been around for 30 years. I'm sure the tech is perfected by now.
That's like saying "buy a washing machine, but don't expect it to wash your clothes". Get them wet sure, but washing will be hit or miss.
