Updating a hacked iphone
This hack enables, along with the previous enabled features, HD Voice for all i Phone models running on AT&T so users can now use the UMTS/HSPA/HSPA network for HD qaulity calling on their 4S and 5.
That’s because latest jailbreaks intentionally disable the OTA update feature in order to prevent users from accidentally upgrading to the latest i OS version, thus losing the jailbreak.
A hacked carrier update that has the potential to deliver improved data speeds is now available to i Phone 5 users on Sprint. A, the device itself becomes more open to an increased amount of bandwidth thus allowing for better throughput of data and data connection. Throttling code was put in place to limit users to a certain amount of bandwidth on 3G only as well and has now been removed. However, Brown explains that this is because it was never throttled on Sprint like it was on the other carriers anyway. There’s no guarantee the update will make a significant difference, and if you already have good 3G speeds, the changes could be very slight.
