Updating iphone to 2 1
It has been quite some time to i Phone firmware 2.2 and i Pod firmware 2.2 releases.
Like all other firmware, i Pod and i Phone firmware 2.2 was not free from bug even after claim from apple about having bug fixes.
Well IPhone Dev-team has clearly warned to all i Phone uses that not to update firmware 2.2.1 as they are still investigating whether or not they are able to jailbreak i Phone Firmware 2.2.1 and i Pod Firmware 2.2.1.
Simply go to Settings → General → Software Update to begin the update.
Apple has provided a list of the security-oriented changes implemented into i OS 9.2.1, and it can be found via this link.
