There’s a new hacked carrier update available for iPhones running on AT&T, which delivers HD Voice, support for Release 7 HSDPA speeds on the iPhone 4S, and a number of other improvements. As always, you don’t even need a jailbroken iPhone to install it.
The update comes from the guys over at iTweakiOS, who have delivered the previous hacked carrier updates for iPhones and iPads on AT&T, Verizon, T-Mobile, and Sprint. This one promises all of the improvements we’ve seen in the previous AT&T update, plus some new additions.
Here are the release notes:
This hack fixes the reported issue of unstable HSPA+ speeds/signal and iPad users having trouble updating and losing all signal. This hack enables, along with the previous enabled features, HD Voice for all iPhone models running on AT&T so users can now use the UMTS/HSPA/HSPA+ network for HD qaulity calling on their 4S and 5. This hack also enables Release 7 HSDPA speeds for the iPhone 4S, giving it a new maximum theoretical downlink of 21Mbps, which AT&T does indeed support. Signal improvements from the previous release have not changed and are still present in this release along with unthrottled LTE and HSPA+. The previous band preferences have been altered this time around but not to prefer bands. It has been reprogrammed to do the following:
– “Optimize WCDMA” which will deliver the fastest available speeds without hindering the towers and other users on it.
– “Set LTE near threshold” which will also deliver the fastest available speeds that the LTE towers support.
