Apple is bringing Personal Hotspot support to the GSM-based iPhone 4 with the release of iOS 4.3 next week, and AT&T says it plans to support the feature. Personal Hotspots let users share their iPhone’s 3G wireless data connection with other devices over Wi-Fi.
Enabling the Personal Hotspot feature will set AT&T’s iPhone customers back an extra US$20 a month on top of the $25 a month Data Pro plan. The Hotspot add-on package includes an extra 2GB of data a month and supports connecting up to five devices at the same time.
AT&T’s iPhone tethering plan customers will automatically get Personal Hotspot support without any extra charges on their monthly bill, too.
iOS 4.3 will be released on March 11, along with Apple’s second generation iPad. The update will compatible with the iPhone 3GS, iPhone 4, third and fourth generation iPod touch, and the first and second generation iPad.
