The answer for me is a resounding YES!
It's all in how you use your phone.
For me it's crucial as I travel a lot for work, and use a blue tooth headset.
I can multi-task, thereby saving myself a lot of time and being much more efficient on the job.
While on a call I can be returning emails or work on our company intranet etc.
This is why I use AT&T and have had nothing but great service and call quality from them.
It was not until the Apple Crybaby's began to complain that AT&T got blamed for having network issues. What most people do not know is there was and is nothing wrong with the AT&T network. All the while iPhones were dropping calls I was enjoying clear conversations on my BlackBerry with no dropped calls.
The fact is Apple is the very best at marketing and conning the public. That is their true area of expertise. I don't know of a better con man that Steve Jobs.
The chip that is in an iPhone on AT&T is not completely compatible with the network, this because Apple bought the cheapest sub standard chip for the phone. This is well documented, but kept hidden away. The only reason I know about it is I came across and article. Stupidly I got busy and forgot to capture the link otherwise I would share it with you.
I am NOT BASHING THE iPhone! I have one myself for my own reasons. But as a phone it's trash. Other than that it has it's purposes.
I'm currently using a Samsung Captivate with great success. And soon I will have an HTC Inspire which will be in my humble opinion the best Android phone and the very best GSM SMARTPHONE one can presently obtain.
There is NO Perfect phone, but this comes very close and will suit me just fine.
Cheers...
