hey there,

so my situation is this: i have an iphone 3G that i tried to upgrade though itunes and now its locked again.

i have tried to unlock it back using Sn0freeze, but it never worked. i read on some forums that there are better softwares that only work on Mac that will do the job.

the phone is softwareless now.

is there any way i can do this on windows7? all help is much appreciated !!
Apple forces you to upgrade to the latest software, otherwise, you can't do anything. In your case, it's 4.2.1. You will have to unlock it using Ultrasn0w or Limerain. You will also need to upgrade your baseband to that of the iPad. You wouldn't be able to unlock it otherwise.
probably it was updated to a not unlockable basband which means your phone is working but with no service right ?
and no carrier options , ultrasnow wont work, oh i just finished reading your post , well since its a 3g phone and your ok with 3.1.3 software (faster ) use it or get the 4.1 os file , then via itunes press shift then restore then in the windows choose the ios file you downloaded let it restore , when it does and it turns on tell me and ill guide you , probably you will be stuck with the itunes recovery pic with a slider and emergency call ...,

after that use redsnow to jailbreak it , once you have cydia , repeat the process with itunes but this time only tick install ipad baseband, hopefully when its done , and your phone powers ,go to cydia , manage sources, repo666.... then install ultra snow this will get your service back since you have the ipads base band , if you feel uncomfortable doing it let anyone with knowledge fix it or you will brick it .
ok i used redsn0w with the ios 4.2.1 ! and following all the steps it worked fine...and the phone was extracting the update files...then it rebooted and i got back to the screen showing the itunes logo with the plug to activate...

now what?
is there a slider down the screen ?
Dope14 wroteis there a slider down the screen ?
no after the Redsn0w finished and restarted there was no slider..

i restored it back using itunes... and voila there is a slider and an insert sim to activate message.. now back to point 0 i guess.
which boxs you ticked with red snow???

nothing in my inbox are u sure u typed the right adress?
you have to update your baseband to the ipad baseband 6.15.00 that's the only way, you should check the "install ipad baseband" in redsn0w



and don't ever restore/update the phone from itunes again or else you'll have to go through other ways of kicking the phone out of DFY mode
