About iPhone / iPad / iPod Firmware:

iOS (iPhone/iPad/iPod Firmware) is a collection of firmware update files (IPSWs) for Apple's popular iPod and iPhone devices. The IPSW files provide a very quick method for updating the software on your iOS device via iTunes.
Install this firmware and your device can benefit from improved system stability, network-related functions and performance, enhanced touch experience, various fixes for problems encountered throughout the device's usage time, as well as several other changes.
Bear in mind that, before you get this release, you must check to see if the available firmware is developed for your model and SKU (stock keeping unit) – if you apply an incompatible software, the device will encounter serious malfunctions and can even be rendered unusable.
Please make sure the you reboot your device after the update process is complete and check to see if you have the latest available iOS version.

It is highly recommended to always use the most recent driver version available.
Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.

2. Also will your custom firmware ask for activation or I will be hacktivated as default?
   Actually I heard that I can fix battery problem by activating my iphone with the oficcial sim (I have one), I want to try that and I was looking for a solution to restore my already 'hacked' iphone 3G with 4.2.1 ios and 6.15.00 baseband because I need it to be NON-ACTIVATED nor hacktivated but ultrasn0w automatically makes it hacktivated.
   Please kindly comment.

3. I'm on 3.1.3 ios and 6.15.00 baseband right now!!! Your video is great. Thank you much.
   I want you to upgrade your video a bit because it might not be understandable to some newbies (i'm not registered on youtube so i write it here):

   1) Description says 'How to downgrade iPhone 3G iOS 4.1.2 to 3.1.3 without SHSH and BATT ISSUE FIX'
   i think you misstyped with 4.1.2. Change it to 4.2.1. It might confuse some people.

   2) Step 6 says 'unplug usd cable from your computer not phone' I think you should add to step 6 'then plug it to computer again'

   3) Between step 2 and step 3 I think there should be step 2.5 that says 'after you started iREB process iTunes will open automatically you need to close it till the iREB finishes its work'

   Regards!!

4. I have a 3G with 4.1 and baseband 6.15. Should I upgrade to 4.2.1 official firmware before applying this custom firmware?

   I haven't tried, but I have a feeling the official Apple firmware won't work on my phone due to the baseband conflict.

   Any tips for me? Thanks Charles rosen forma sonata pdf files.
