Re: Call & Connect PC with Wi-Fi or Internet Sharing at same time?
Both CDMA and GSM have the capability of doing simultaneous data and voice. It's just that Sprint and Verizon have decided not to dump the boatload of cash into their networks to do it right now.
AT&T and T-Mo spent their money on other things like simultaneous data and voice instead of rolling out 4G a little faster. As such, when Verizon and Sprint fully roll out their 4G networks, AT&T will be hosed
