On Thursday October 8 iPhone released an upgrade version 3.2.1 for its existing OS 3.1.The new OS also includes Xcode 3.1.2 and is free from some general bugs present in the previous versions like sporadic issue(wake up issue in sleep mode).
The greatest advantage of this upgrade is that apple is offering it as free upgrade and the OS 3.1.2 is compatible for all the iPhone handsets and iPod-touch. To upgrade your OS you have to connect to a computer with internet connection and download the upgrade via iTunes. After plugging in your iPhone into computer just press the update tab .
The OS brings with it solution to the ‘sporadic issue’ that prevents the iPhone form waking up from sleep mode, causes device to crash during video streaming .The problem of interruption in network services which persists until a restart of iPhone .The bug of dubbed ‘comma mode’ in user forum discussion has also been resolved .It now also supports the creation for web applications that are optimized for Safari browser of iPhone.
The upgrade size is of around 200 MB. On one hand the upgraded OS seems to sort out the major bugs on the other hand it seems to extend the age old problem of ‘Limited Battery back-up’.The new OS seems to to consuming somewhat more battery than the previous version causing Diminished battery life.
Another problem with the upcoming upgrade is that of wi-fi. The Wi-Fi glitch problem still persists like in version 3.1. and does not seem to working fine. For users who use Wi- fi network regularly ,should wait for a while for another upgrade having a solution to the problem.
For iphone users currently using version 3.1 ,I recommend to upgrade it as a necessary upgrade required as it has sort out several of the bugs .The new version is definately an alternative solution unless next upgrade is released. To update your iphone you need is to download the update via iTunes. But if you are using a jail broken iPhone, wait until the Jail-break for the iPhone 3.1.2 is released.
