One feature that stands out on the CDMA version of iPhone 4 for Verizon Wireless is that it’s running iOS 4.2.5 and supports mobile personal Wi-Fi hotspot (AT&T iPhone 4 and Verizion iPhone 4 comparative review). Personal hotspot, commonly known as Wi-Fi hotspot or simply hotspot (where personal in the term probably to indicate it’s for personal use only), is an access point that offers Internet access typically via Wi-Fi wireless technology through the use of a router (iPhone or mobile phone in this case) connected to a link to Internet through mobile network via 2G, 3G or 4G.

In other words, iPhone users on Verizon Wireless carrier network can turn its iPhone into a personal hotspot which allows other computers, tablets, gadgets, smartphones, peripherals or any equipments with WiFi capability to connect wireless to Internet via iPhone, provided you have subscribed and paid for the proper data plan.

In essence, the “Personal Hotspot” feature is similar to Internet tethering function built-into GSM (AT&T) iPhone, which works only through device connected to iPhone via USB or Bluetooth, while hotspot allows selection of connection through Wi-Fi wireless connection, in addition to USB or Bluetooth.
