fast way to delete all contacts?

[ianbroste]

If my Iphone is jailbroken and I do this, will it wipe out that as well?

If you go into

Settings>General>Reset>Erase all content and settings

It should erase your phone (I think). This is what they do at the apple store when they swap out your phone for an exchange.

I tried getting rid of my contacts by going to settings - general - reset - erase all settings and my phone locked up. I tried powering it down but when I turn it back on I just get the apple stuck in the middle of my screen. This is a very old iPhone3. Any suggestions?

^^Yep..... that method doesn't work and will lock up the phone.

If you don't care about what iOS version or modem firmware version (for a future unlock), restore current version w/iTunes --- after the restore and iTunes recognizes a new phone, just cancel and disconnect. Virgin iPhone.

If you want a lower version and keep the older unlockable modem firmware, restore with a custom firmware.

Remember when iTunes wants to set up a new phone, cancel! You could even avoid that by disconnecting when iTunes displays the 10 second countdown window after the restore is complete.

Thanks for the info. I tried this but was unsuccessful. My computer did not even recognize my iPhone. Any other suggestions?

I had an issue with this, this evening so I will post my situation / solution:

iPhone 4 (newest 4.2.7 firmware), not jailbroken, Verizon).

I had 507 contacts that had imported from my email contacts on my work computer. It is an exchange account I imported from my work computer to mail.

I was using an exchange email account so when trying to sync with the different things in iTunes: Mac Address Book, Gmail, Yahoo (with all of these having no saved contacts within them) and it would not override / delete the contacts on my iPhone even when I told it to through iTunes.

I had to physically go on the iPhone into Settings --> Mail --> and turn off the option of the mail uploading my contacts from that network. Then it asked me if I wanted to delete all the ones on my iPhone I clicked YES and bam, all my contacts were gone.

Hope this information can help someone.
