Many people have asked us about how they can get the best coverage performance from the iPhone 4 when it launches on Friday. So we’ve assembled some tips based on our Next G™ network testing.

The first thing to know is that the iPhone 4, without the use of accessories, is approved by Telstra for handheld use in metro and major regional coverage areas. These are the areas marked as “voice, picture, TV, video and broadband” on the Telstra Next G™ coverage maps that can be found here.

Tip 1 – Enjoy Blue Tick equivalent coverage on iPhone 4 in regional coverage areas with an approved bumper or case

The great news for our regional and rural customers is that an approved rubberised bumper or case can help to maximise the coverage performance of the iPhone 4. In fact, the handheld coverage performance is improved so that it is equivalent to one of our Telstra ‘Blue Tick’ devices.

We award our Blue Tick to mobiles that have the best coverage performance and recommend them to customers working or living in regional and rural coverage areas.

A bumper, in case you’re wondering, is a rubber accessory that fits snugly around the edges of a mobile phone.

Tip 2 – Enjoy the best iPhone 4 coverage in metro coverage areas

To help maximise coverage performance in metro and major regional areas, Telstra recommends that customers team their iPhone 4 with an approved rubberised bumper or case.

We’ve found that an approved bumper or case can also improve the consistency of data speeds when customers are using a fast network like the Telstra Next G™ network. So if frequent mobile internet is important to you, we suggest you grab a bumper or case.

Which bumpers/cases have been tested by Telstra?

So far we have tested two bumpers and a case. Details of the Blue Tick equivalent cases we have tested can be found here.

How we test
Telstra uses a two-phase methodology to test the coverage performance of each mobile phone model it offers to customers. The first test is conducted at Telstra’s anechoic chamber in Sydney and examines a mobile’s handheld receiver sensitivity. The second test is conducted out in the field. Testing looks at elements like voice quality and how successfully a handset makes and receives calls at the edge of coverage. Check out how it’s done here.
