into iOS5.0.1 (untethered jailbreak)

it has been a long wait since the last iOS update for my iphone... finally another post in this long forsaken blog~

let's jump straight into the subject

prerequisite:
1) updated itunes (v10.5.2.11)
2) iOS5.0.1 firmware (9A405)
3) A4 based devices (not for iphone 4S and iPad2)
4) redsnow (0.9.10b3)

moving from 4.3.1
the steps are pretty simple, but it did took me some time to get this done
1. backup phone for one last time
2. power off your device and disconnect from computer
3. put device in recovery mode (with cable and itunes logo)
* while pressing home button, connect device to computer
4. open itunes, recovery mode will be detected but do proceed to check for updates
5. shift+click on recover button and locate the downloaded firmware ipsw file
6. wait for installation to complete
7. iOS will be updated to 5.0.1
8. complete the setup on the device
9. restore phone from latest available backup

jailbreakin'
1. run redsn0w as admin
2. click on "jailbreak" button
3. follow onscreen instruction to place device into DFU mode
4. once prompted, check "install cydia" option
5. redsnow will run and complete the jailbreak

post jailbreak (optional)
- get cydia apps, among my favs are:

>> Installous 4
* required if you need to sync previously downloaded apps

>> Copic
>> MultiCleaner

- non repos:

#note: i did encountered a few glitches during the upgrade, which had caused some delays and frustrations... here's some sharing in case you get into the same problem

error 3194
- make sure your firmware file version is correct and not corrupted
- check windows hosts file is not diverting gs.apple.com
C:\Windows\System32\drivers\etc\hosts
- download tinyumbrella and uncheck the option "Hosts point to Cydia on exit box"

error 1600 (during iOS upgrade)
- make sure the device is in normal recovery mode (not DFU) during upgrade

other errors
- make sure itunes is upgraded to the newest version
- try reconnecting the device to pc and restart upgrade process
- if still fails, try upgrading from another computer

installed apps not synchronizing automatically
1. install installous
2. connect device to computer
3. drag the apps icon from library to devices

i'm relatively new to iOS5, so it'll take some time to browse and test out the new features... the notification center looks very promising though~ but when i'm through with it, i might be posting some rants and complaints if i have the time~

last but not least, "happy new year 2012!" to all, including myself :D
