iPhone Software Update times out

[Catawba]

Friends, I was updating the iOS in my iphone and whenever I try to do that it sows me the message saying that "There was a problem downloading the software for the iPhone. The network connection timed out." This message comes every time when I try to update it using iTunes. Earlier also when I was updating my iPhone 3G the same problem occurs and now it is with my iPhone 4. Please help me to get out of this.

I also faced the same problem and was not getting the solution for a ling time and finally I point out that the antivirus program that was running in that. I disabled the Anti-Virus program temporarily and downloaded the update without any problem. And after installing that again I enabled the antivirus program and it is done. You should also try to update by disabling the antivirus if there is any.

This may not be only antivirus that is aborting the update process. There are many other possibilities for that like the firewall that is that may be blocking the download process. It may also be your router that is blocking the port for download. There is also a possibility that is uncommon but may cause the problem that is TCPWindowSize parameter in the registry is incorrectly set. See for these possibilities also.

Firewall is not the problem for this because I have tried this after disabling the firewall protection. I would like to tell you all that the problem is not with downloading. I can download the file without any problem. The problem arises when I go for installing the update. The file for the update is processed by the iPhone Software Update. I hope this will help you all to provide the possible solution for this.

As you told that the problem is coming after downloading the file. So I think that the downloaded file is corrupted because it is not downloaded properly. You should download it again from internet and see the size of the file. The file size should be 391.184 and if you have the file size very different from this then the problem is with the download.
