How to bypass and reset an iphone 4 WITHOUT COMPUTER OR ITUNES?

I forgot my iphone passcode and it is NOT backed up with icloud itunes etc. I need to unlock and reset my pgone so i can sell it
Any help

I believe you may have hit a wall… The idea is that you can't access it without the passcode. Your only options are to contact Apple for a resolution or attempt a memory wipe with iTunes or a computer. Jailbreaking might have an option (but this will void the warranty).

When most people are ready to sell their old phone, they do a "hard reset." Turn the phone off. Hold the on button and the center selection button down at the same time. This should reset the phone to its original iOS. Then, most people would also remove their personal SIM card from the phone before selling it. This is what Apple recommends. All a purchaser has to do to make sure the phone works, is place their own SIM card from a compatible version of the iPhone and make a call. Note: if the phone is still locked to a particular carrier, it will only work for the purchaser if they are on that company's service. Unlocked and reset, are two different things. If you have completed the contract on the phone, or upgraded, the carrier you were using will have the Unlock code that must be entered to switch the phone to a different carrier… So a buyer must either be on the same carrier you have been using, or the phone would be useless for them. If you go to Apple's website, you will notice that they sell Unlocked phones at a higher price than those locked to a particular wireless provider. You will also see a choice between CDMA or GSM for your unlocked phone purchase. (These stand for different frequency bands being used by the wireless phone companies.) Only Unlocked phones can be switched from carrier to carrier… And then only if the wireless provider desired is using the same type of frequency the phone chip is set for. Sprint, for example uses CDMA while AT&T uses GSM. When you sell the phone, either contact your carrier for an Unlock code and enter it, or make sure you advertise it as being set to the wireless service provider it was used with. That being written, there's a big after-market for the phones to replace broken, damaged or lost ones.

Also, many people now know, or should know, that there's a database of reported stolen and lost phone serial numbers being used by the phone carriers. Usually, if a phone has been reported stolen or lost, and it appears in that database, it will not function, even with a new SIM, or an already activated SIM card installed. That is why it is important for anyone buying a used phone to have a SIM card that is already activated, and try it in any used phone before they purchase it, to be sure they aren't wasting their money on a phone that has been reported lost or stolen… Or is defective. Even if you broke your phone, and are buying a used one to replace it, the SIM card should still work in the phone you are buying, if the phone you are buying isn't defective or on that list, and if it is either unlocked or set to your carrier's service.

Thanks but that didn't work
