How to bypass iPhone 4 icloud passcode

SOURCE: I forgot my passcode to unlock my iphone

It depends on the severity and the settings you have given the iPhone and whether you have the computer that you synced your iPhone with... Here's the full explanation. I would recommend reading the second paragraph first, but the solution if you really forgot your password is in the first paragraph. 
==If you have the computer you synced your iPhone with==
If you cannot remember the passcode, you will need to restore your device on the computer that was used to originally sync the iPhone or iPod touch so that you can reset your passcode and resync the data from the device (or restore from a backup). If you restore on a different computer that was never synced to the iPhone or iPod touch, you will be able to unlock the device for use and remove the passcode but your data will not be present. Refer to "Updating and restoring iPhone and iPod touch software."

"If you enter the wrong passcode too many times, you'll see a message that says "iPhone is disabled" and to try again later. If you repeatedly enter the wrong passcode, iPhone or iPod touch will be disabled for longer intervals, before you can try again. After too many unsuccessful attempts, you won't be able to try again until you connect to the computer you normally sync with. Note that starting with iPhone 2.1 software, there is a setting to cause the device to erase itself after 10 consecutive incorrect password attempts. This setting is off by default. It  can be turned on by tapping Settings > General > Passcode Lock after you enter a correct passcode."

==If you don't have the computer you synced your iPhone with==
If you don't have the original computer the iPhone synced with, the only solution is to force your iPod Touch into recovery mode and then restore it. You will lost all the data on the iPod Touch, but after this method is done, everything will work. You can find the steps to solving this problem here:

SOURCE: iPhone sync with Outlook Calendar - Appointment time put on iPhone 1 hr later.

This solution pertains only to the one hour time difference people notice upon syncing to MS outlook.

In iPhone, there are two areas where you have an option to change your time settings.

1. When you go to 'settings', then to 'general', you can set up time and date, and also 12-24 hour format. Please note that changing the time here DOES NOT correct the problem, despite iPhone displaying correct date, time and time zone. Many people in this thread have stated that the problem persisted despite them setting appropriate time zone.

2. When you go to 'settings', then to 'mail, contacts and calendars' row (NOT the 'General' row) - you get an option to change your time zone at the very bottom of all the choices. You will see that wrong time zone is selected here - likely cause of the problem. Correct this choice and the one hour discrepancy between appointments in outlook and iPhone disappears.


Additional problem solutions - in the solution No. 2, if you set 'Time Zome Support' to 'ON', then all your appointments in the calendar will be displayed in the time zone of your HOME address. In other words, for example, if you are a person in central time zone, your appointments will be displayed ALWAYS in central time zone format - they will NOT change automatically when you travel from central time zone to eastern time zone. On the other hand, if you set the time zone support to 'OFF', then all your outlook appointment display times will change and adjust according to any time zone you travel to - This is often an inconvenience since most of us would like to remember our appointments as they were made in our home time zone, regardless of what time zone we traveled to.

Please note that the above solution pertains to only display of appoint times in outlook - This solution does NOT relate to the time displayed by iPhone and how that displayed time adjusts when you travel to different time zone away from your home time zone. This second issue is addressed below -

You can get your iPhone to display the current time in two ways -

1. Either always show the time in your home time zone, regardless of where you are (i.e., a person from Texas central time zone can set up to see the time always in central time, even if he/she travels to another time zone). This display setup is good for people who always think of time in their home time zone and then do mental conversions to reach at the local time zone time.

2. On the other hand, you can get iPhone to do this for you and change displayed clock time automatically to the local time zone that you have traveled to, away from your home time zone. Please note that enabling this capability in iPhone has no bearing on how the appointments are displayed in MS outlook.

Go to 'Settings'. Go to 'General' tab. then click on 'date and time'. Pick the 'set automatically' option to 'ON'. Now, the iPhone will automatically adjust displayed time to show the current time in which ever time zone you travel to.

If you set the 'set automatically' option to 'OFF', then you can select your home time zone. Then, the iPhone will always display time in your home city time zone and will NOT change even if you travel to a different time zone.

So, in summary, there are two places you need to adjust the time zones in iPhone - to do two separate tasks, first task of displaying appointments always in your home time zone upon syncing with outlook thereby avoiding the one hour skip; Second task of getting iPhone to display either your home time zone clock, or getting it to adjust current time to reflect the time in new time zone you travel to.

Hope this helps.
