Unlike the iPhone 4 launch, where Telstra was the first to release its pricing plans, Australia's largest telco was more coy this time around. It waited until Optus and Vodafone released their iPhone 4S plans before unveiling its own.
The Telstra iPhone 4S plans seem very competitive. The hero offer is the 16GB iPhone 4S which is available for no extra monthly cost on Telstra's $79 Freedom Connect plan over 24 months.
All in all, the iPhone 4S is available on four Telstra plans -- $59, $79, $99 and $129 with varying monthly handset repayments on top of the plan cost depending on the model and plan you choose. The top line 64GB iPhone 4S will cost an extra $13 on the $59 plan ($72 per month), $9 on the $79 plan ($88 per month), $5 on the $99 plan ($104 per month) and $5 on the $129 plan ($134).
Like Optus, Telstra will not offer the iPhone 4S on 12 month plans. This leaves Vodafone as the only Australian telco to sell the device on 12 month contracts.

Telstra will open its stores across Australia from 8am on Friday for consumers to purchase the iPhone 4S. The telco also says you can pre-order the phone on its Web site -- though it currently shows a "register your interest page", Telstra says it will begin taking orders "later today".
