has anyone had problems with updating their iphone through itunes ?

not had an issue up until the 4.2.1 and 4.3 updates

it seems to take a long time to connect to the update server and then when its preparing the phone for update comes up with an error relating to the usb ports on my pc.

which meant i had to restore the phone which is annoying.

once the phone is restored, i dont have any issue with the usb ports when syncing my iphone in itunes and when transfering music to it.

is it best to click download only and then update the phone with the update on my pc ?

I have just got an iphone 4 and i was going to update the software to version 4.3 however intunes downloads nearly all of the file and then it says that my internet connection was interrupted. This has happened numerous time now.

I did notice in the that few seconds the connection drops however it only happens with this update, i have had numerous versions on my 3gs and i also download other files with no problems.

Could itunes be cutting the connection? I am going to try and download it from another wifi connection and see what happens.

it could be but i think the itunes server must be overloaded or something as i've only had issues with the last too updates.

from now on i'm going to only update the phone when necessary to avoid these errors

Only had my iP4 for two weeks. About a week into it iTunes informed me that iOS4.3 was available. It downloaded with no problems. However it took 3 attempts to update the phone. IIRC it could not validate the download.

I tried to update the phone using my parents wifi connection and the same result. Looks like i will not be getting IOS 4.3
