The reception for my place almost the same between a400 and a460. My apartment complex has bad reception ( 2 bar all the time). I had a400 before return it and purchase the a460 The polyphonic sound is much better but not suitable for business use. It is much clearer than the a400. I can hear much better and other party recieve my voice better. I like blue color. External LCD will be very helpful for me.
a460 is CNET new product of the year for last CES.
If you can wait, I'll definitely wait for a500. Retaill will be around 250-300. Check
www.phonescoop.com for some information. That's ll be true 3G phone. a460 is 2.5G technology with less data transfer. Sprint will hold the lauch of 3G around August or September.
I believe Sanyo has better reception among the SprintPCS phone especially the slim new one but I heard battery life is not so great.
