If you don’t have a sim card for your iPhone 3GS or 4 and you updated to 5.1 then you will be unable to skip the “activation screen.” This can be extremely frustrating since most likely all you want to do is use the iPhone as an iPod. Follow the instructions in the video below to begin using your iPhone in no time.

    Man, you are an angel sent from out of this world. You solved my all my iPhone problems. Big ups and I will definitely be following for more tips and tricks. God bless you!

  50. Abel says:

    Thanks a lot it worked on my iphone 3gs, Activeted and know I need to unlock the phone to use it universally. please post or upload video how to unlock the phone.

  51. Kiden says:

    Abel, I agree with you. The video is really helpful. Towards the end of the video Ian explains a little bit about unlocking. It is easy. Simply go to Cydia and search for Ultrasn0w (the same way you searched for Rocky racoon). Install it and you are good to go. Just in case it still does not read your sim card, you may have to install ipad baseband.

    • Abel says:

      Thanks Kiden, I did download and installed redsnow, but it still says no service. I guess will have to install ipad baseboard. Could you please post the links and how to install ipad baseboard. (By the way I’m new to this hence need to know, mine is a iphone why install ipad baseboard).

  52. Aaron says:

    Hi, Thank you so much, it worked. Now i have another issue.

  59. lexter says:

    certain operation (like the a5 jailbreak)are disable due toincomplete itunes libraries. please be sure the latest itunes is installed..

    coudn’t load mobiledevice.dll

    need your help guys..

  60. Ad says:

    why does i tell me activate device when i click jail break .wasnt this entire process to get passed the activaion screen…..upset

  61. RiskOn says:

    Well looks like I messed this up really nice.

    I tried to downgrade but after a few failed attempts at entering dfu mode, now my power button wont work at all!

    Also my iphone was restores to factory settings (dumb idea) thinking that maybe there was some app messing with my power button.

    Now I cant enter dfu mode, recovery mode or anything, and I need to activate the phone again, is there any way to hactivate the iphone without entering dfu mode?

    Please help I have been up all night trying to find the solution but the only thing I keep reading is that I have to replace the power button, which is not possible here.

    With all the apps and hacks out there I have to think there would be a solution.

  62. Sally says:

    You are amazing!! u saved me so much money …. I reset my phone because i lost my password and now I can use it without the sim!! Thank you so much!

  63. Meagan says:

    If only I knew what firmware link I needed. Luckily I’ll bringing it to a friend in the next few days who will know. I hadn’t had my iphone updated in some time since my itunes was out of date. It’ll be good to be able to get into it again, since I honestly used it for everything else but a phone.
