Thanks for all of your feedback on Telstra’s Android device range. Here are some answers to some of the commonly asked questions you’ve posted.
A few of you have asked how the update to HTC Desire’s operating system is tracking. I can confirm that we’re set to introduce Android 2.2 (aka FroYo) within the next four weeks. As a background, Telstra always puts its firmware deployments through rigorous network and performance testing — and this takes a little bit of time.
It’s also important to note that HTC works with hundreds of operators around the world and Telstra, like those operators, has had to secure a place in HTC’s software deployment schedule. Again this takes time.
Many of us at Telstra are HTC Desire fans, so we’re as keen as you to make FroYo available. Thanks for your patience while we finalise testing.
We recognize customers want maximum control over the apps saved to their phones. The team is currently working on future user interface designs for Next G Android smartphones that reduce the number of shortcuts saved to device menus."
Assuming the date doesn't slip, sometime in the next 2 weeks.
