The iPhone 4 will be available on the $49, $59, $79 and $89 consumer cap plans (over 24 months), which include 1GB, 2GB, 2GB and 3GB worth of data respectively. On the plans, the 16GB handset is free on the $59 plan, while the 32GB is free on the $79 plan.
It will be interesting now to see what potential iPhone customers do. A lot of iPhone 3G customers will be looking to upgrade and there seems to be a lot of chatter from Optus customers looking to leave the network. But consider the difference in data allowances between Optus and Telstra – 1GB compared to 200MB for a $49 plan (and 3GB compared to 500MB on the higher end of the scale).
