You have a lot to learn.
Multi-tasking is completely different from surfing the web while talking on the phone.
Presently, 3G phones on Verizon's CDMA network, are unable to talk and surf at the same time due to NETWORK limitations. It has absolutely nothing to do with the multi-tasking ability of Motorola phones or phones running Android.
As stated previously, Verizon LTE phones will allow for talking and surfing over LTE and Wifi.
Android allows true multi-tasking, iPhone does not, this is one of the ways they achieve smooth performance.
