I used to update my iPhone 4S applications whenever a new update is available, but at this time, "unknown error" displays after entering my apple id password. Anyone who could help, whom they might have experienced? Thanks
When you say you reset your network settings, what do you mean, exactly?
I saw another post on this issue, and the poster indicated that they resolved the problem by turning off their cellular date option and wifi options in Settings, and then turned them back on.
Also, resetting your phone may help - press the Home and Power buttons at the same time and continue to hold both down until the Silver Apple appears. Once it is back up, click on the update option and see if it fixes the problem.
If none of those things work, then need to have details on what you did to reset your network settings....
