The Netgear AirCard 790s (also known as the Telstra Wi-Fi 4G Advanced II) is the first device sold by Telstra to support LTE on all current and future bands, and support LTE-A CA (carrier aggregration) across multiple bands. It’s also the first hotspot to carry the new 4GX branding. You’ll always get the fastest speeds possible, today and into the foreseeable future, with support for LTE on bands 1 (2100mhz), 3 (1800mhz), 7 (2600mhz), 8 (900mhz) and 28 (700mhz). And 3G too, so you’re covered everywhere. The 790s also supports LTE-A CA on bands 3+28, 28+7, 3+7 and 7+7 – for typical speeds of between 2Mbps to 100Mbps in a 4GX area. In a standard 4G area, you should see typical download speeds of 2Mbps to 50Mbps.
Telstra today have announced that their new 700MHz network will go by the name of ‘4GX’, which joins Optus who have named their 2300MHz network ‘4G Plus’.
(you may remember this was quietly mentioned at the start of last month ;P)

The 700MHz network has started being trialled from earlier this year, and is gradually getting bigger ahead of the ‘big switch’ on January 1st, when the 700MHz spectrum is officially available for use across Australia.
Come here and you’re curious as to how these work without a jailbreak? Or are interested in an overview of making your own, then read this post about carrier bundles.
After Apple released iOS 6.1 earlier this week, it was time to update the carrier bundles yet again!
One of my favourite things about the iPhone is that it’s fairly painless to throw another SIM card into your iPhone, and have all of your carriers settings just work (internet, MMS, voicemail, and tethering if your carrier allows it). The way this magic works is that Apple actually has the settings for all of the official iPhone carriers preloaded into iOS. If you throw in a SIM from a supported carrier, the settings are simply loaded and away you go. These are referred to as carrier bundles (or, carrier settings according to Apple).
Carrier settings updates are small files (about 10 kb) that are installed on your iPhone or iPad (Wi-Fi + Cellular models). Carrier settings include updates to Access Point Names (APNs), MMS settings, features such as tethering, and default apps such as Stocks, Maps, and Weather.
On your iOS device, they live at
/var/mobile/Library/Carrier Bundles/ – bundles that have been updated with iTunes, or pushed over the air
/System/Library/Carrier Bundles/ – stock bundles that ship with iOS
On your computer side, they can be found at
~/Library/iTunes/iPhone Carrier Support/
If you haven’t ever had iTunes prompt you about a carrier update, this folder probably won’t exist.
Carrier bundles themselves are simply .zip archives, but with a .ipcc extension instead. They’re named after your carrier, and may also say whether they’re for your iPhone or iPad (Telstra_au_iPhone.ipcc)
Since there doesn’t seem to be an easy and straight through guide for unlocking your iPhone, thought I’d quickly throw something together.
Unlocking your iPhone is great. It allows you to put in other carrier’s SIM cards. This is great if your telco isn’t cutting it and wish to move networks and keep your phone. It’s also handy for when you travel; picking up an international SIM is much cheaper than using your local SIM card and then roaming overseas. Oh, and it increases the resale value; anybody on any carrier in the world can use it now!
Around the world, most telcos will allow you to unlock your iPhone. Here in Australia, all telcos will unlock a post-paid iPhone for free. If you’ve picked up an iPhone (3GS) prepaid, you’ll have to cough up an unlocking fee. Overseas, companies such as AT&T will only unlock your phone when you’re at the end of your contract (officially). Apple has a list of carriers that will unlock your iPhone on their website.
If you contact your carrier today, chances are they’ll tell you it may take a few days (up to 72 hours) for things to happen, and at that point you need to connect to iTunes and restore. However, as of iOS 5, and the new PC-free initiative and methods, unlocking has become much easier. There’s no need to do a great big backup, and then restore just to unlock your phone.
