Vodafone is yet to release pricing structures at the time of posting, but has said it will offer the iPhone 3G on both pre-paid and contract plans. A spokesperson from Vodafone said the release of their iPhone 3G pricing plans is imminent.

The only local carrier yet to offer the iPhone 3G is 3 Mobile, which has setup an online petition to convince Apple to allow it to also sell the much anticipated handset, and is hopeful of striking a deal soon. 3 Mobile customers can sign the carrier's Web petition and send a message to Apple, or SMS the word 'iPhone' to 333000 to receive a form allowing them to send comments directly from their mobile.

Apple also set a general early July date for the release of the iPhone 2.0 firmware - the software driving the new enterprise functionality and features of the new handset.

Support for Apple's iWork suite and Microsoft Office Applications, access to Microsoft's Exchange ActiveSync, the addition of VPN capabilities supporting Cisco IPsec and wireless encryption, and the iPhone Configuration Utility allowing greater security capabilities for IT administrators will facilitate the iPhone 3G's enterprise adoption.
