  • iPhone 4.0 Beta FAQ


    Some popular questions are:

    1. How do I get Beta 4.0!? How much should I PAY for a Dev spot?

    You must first download 4.0 Beta via a torrent file or from the Apple Dev portal. (Search on google)
    You must have access to a dev account. (This forum has Users selling Dev spots. Also see Ebay)
    Anyone can buy a Dev account for $99.00 and they can then add 100 devices
    Prices for Dev spots seem to be a reasonable $5 to $10 donation.

    2. What is a UDID and How do I find it?

    A UDID is each iPhone's Unique Device ID (40 hex characters)
    To find it:
    You connect your iPhone to itunes

    Click on the actual serial numbers for your iPhone in iTunes summary page:
    Serial Number:*9xxxxxxxxxx (11 digits)

    When you click the serial numbers it will change to identifier:
    Identifier (UDID):*xxxxxxxxxxxxxxxxxx.... (40 digits)

    2. Is 4.0 Beta or a real release and when is it being released to the public?

    4.0 is a Beta release for developers to incorporate support for the new capabilities of 4.0 into their software

    The legitimacy of using 4.0 is kind of shady. While apple does allow developers to seed their apps to "testers" who don't have to be developers, apple agreed to allow developers too add up to 100 devices to their lists as to collect crash log info and make debugging much easier.

    Apple do not support or recommend updating at this time (If you are not a developer or tester for a developer). It will not void your warranty but will leave you with a unjailbreakable OS. If you try to update without being on a dev list you may not be able to activate your phone, but some people have managed to circumvent this.

    3. If I upgrade my 3G/3GS phone to 4.0 will it still be unlocked?

    No, and there will not be official Dev Team support for 4.0 jailbreak/unlock until the official 4.0 release.

    4. I upgraded my phone to 4.0 and can't make calls how do I install ultrasn0w or blackrain?

    Due to there not being support for Jailbreaking/Unlocking Installing ultrasn0w or blackra1n is NOT possible.

    5. How do I downgrade the baseband?

    Downgrading the Baseband is NOT Possible.
    Users must wait for the Dev Team to release an Unlock to use other GSM carriers on 4.0.

    6. How do I Unlock/Jailbreak Beta 4.0?

    You cannot Unlock/Jailbreak until the official release for 4.0 comes out and the Dev Team post their update. Beta jailbreaks may come out but will not have official support.

    7. I installed 4.0 Beta on my phone and iTunes won't activate my phone... Help!

    You must have access to a dev account. (This forum has Users selling Dev spots. Also see Ebay)
    Anyone can buy a Dev account for $99.00 and they can then add 100 devices

    8. How do I downgrade from Beta 4.0 to 3.X.X?

    From member rishidhar: I can confirm that I was able to downgrade my Iphone 3GS from 4.0 beta to 3.1.3 (since I did not save my SHSH files) by going to DFU mode and restoring the old firmware using the new ITunes 9.2, The restore fails half way when it tries to downgrade the baseband (which we know does not work). After the restore fails, it puts your phone on the recovery mode loop, to get out of this, I just ran blackra1n when it was on the recovery mode screen, this led to the screen going blank. Keep the sleep/wake and home button pressed until apple logo shows up and it should take you to your home screen eventually. I am currently on 3.1.3 with the new base-band 5.13.03. Hope this helps all the user's on modmyi.com.

    Apple is still signing 3.1.3 so you do not need any special shsh on file to get back to this firmware on a 3GS. Regular 3G users should be able to go back to 3.1.2 as needed.

    9. Does 4.0 Beta upgrade the baseband?

    Yes. There are reports of 5.13.01 out in the wild. It's possible future betas will further upgrade the baseband so no one will be working on an unlock until the final/official release.

    10. Will this Beta version expire?

    Yes. Apple traditionally releases several beta versions before the final public release. Older Beta versions will expire very soon after the replacement is released and you will be forced to upgrade to the most current beta.

    11. Why do I get an error when I install 4.0 beta on windows?

    As of today, April 9, only Mac users can install this onto their iPhone. Windows users will have to wait until Apple fixes the issue.

      What I wanna know is: Is Steve's iPhone jailbroken?
      Because if it's not, he's missing out on all the great things there, and I think that Apple should consider looking at those AMAZING add-ons, fixes, mods, etc. because they make this phone even more user-friendly, they could even help make them safer for the iPhone and less crash-prone.
      Either way, THANK you Steve Jobs for this wonderful thing, THANK you dev's for a job well done, THANK you jailbreaking community for making my iPhone...MINE!

      Select a word and a "Replace..." option appears. Seems to be a synonym type replacement suggestions. Thanks.

      Right, I mean if you are already using beta is it normal to just upgrade to any new betas that come out?

      I am also wondering this...

      I've only used the folders, zoom, wallpaper, and the all-in-one mailbox

      A new software, or one that is being updated, that is ready to be released to users for beta testing in real-world situations. Usually betas have most or all of the features and functionality implemented that the finished product is to have.

      A test of software that is still under development, accomplished by having people actually use the software.

      are updates for me done the conventional way or do i need stealth to upload the new betas every time a new one comes out? do you think this will allow me to do a windows update if it's done normally?

      Even though it's pretty early in the game and there's no telling what Apple might do with resetting it, but has anyone thought about setting up a forum on here for Game Center so we can get names/aliases together?

      Here's a small tip to make finding the UDID, and copying it correctly without error.

      Plug in iPhone, iTunes doesn't even need to be open.
      TOP menu, click on the Apple logo.
      Click 'about this mac'
      Click 'more info...'
      under contents there is 'USB'
      then under 'USB High-Speed Bus' click iPhone
      the serial number is the UDID, and you can highlight copy and paste.

      I am able to run Tap Tap Revenge 3 on 4.0 without any issues (besides the dang Radio Disney ad popping up at launch...dang Disney). Right now, when you double tap the home button, the game is paused, but it doesn't allow you to select any other app in the bar at the bottom. It will still do the countdown when you tap resume though.

      No problems with wifi so far. The only major problem I had so far was with downloading a song from the iTunes app. When it tried to finish processing the download on my phone, it sent my phone into a never ending reset loop. It would bring the home screen back up after resetting, but about 20 seconds later, the phone would restart again. I had to quickly get to the download and pause it before it tried to finalize the download to stop the cycle. Not sure when it will get fixed or when I will get my song now.

      I'm having problems with wireless 802.11n when the router (a Belkin N1) is set to dual 20mhz/40mhz bandwidth. The iPhone sees the router, but won't connect. Other people on other forums have reported similar problems.

      Obviously, this didn't effect my 3GS before the software update.

      What's perhaps more interesting is that the wifi problems with the iPad are very similar - that suggests to me it's probably fixable by software.
