How do I jailbreak/unlock 3G phone without valid sim card?

Asked September 22, 2012 at 12:34am by Juicer_90 | 2267 views | Mark as Spam
I got an Iphone 3g as a hand me down from a cousin. Since its from another country, it does not accept any of the sim cards here. I've followed the redsn0w/ultrasn0w method for 4.2.1 (He had updated it to the same) but everytime I try it, redsn0w crashes. Do I still try redsn0w? If so,which version? Also, can I access Cydia without any sim card post jailbreak? I am using Windows XP SP3 as OS.

Do not keep on trying the jailbreak methods as it has a chance to void the warranty and brick your phone.To unlock an iPhone the remote unlock service would be a better option because,you need not give your mobile to someone else nor do you have any chance to enter the wrong unlock codes.To get such an unlocking service for your iPhone 3G approach Theunlockarena.com and by submitting the country and network to which the mobile is locked to you will be able to remove the restriction from the respective network. This will be a permanent unlocking solution.You only need to enter the sim that is not accepted in this unlocking process...hence it will be very suitable for you.

The Sim card really shouldn't matter, since the jailbreak doesn't access any of the information on the card (the Sim card only holds information specific to your mobile carrier).

I'd guess there's something else going on. If redsn0w doesn't work, I'd try absinthe (which I prefer anyway). But check your iOS version and baseband. If you've upgraded to iOS 6 it won't work, and if you have anything other than iOS 5.1.1 Apple won't authorize it (which is required). What's worse, if you haven't already loaded 5.1.1, you won't be able to now!

If any of those apply to you, I'd simply sit on your hands until someone finishes jailbreaking iOS 6. There's one version available now, but it only works on 3gs and 4 phones.

Finally, remember that the phone MUST communicate with Apple for it to work (the phone, NOT the jailbreak), so make sure you're in range of a wireless network when you try it.
