This is my first post on everythingiCafe and all I ask is a pointer in the right direction.
Last August I bought for my kid a jailbroken iPhone 3G iOS 4.2.1 (8C148) for use on T-Mobile voice/text with WiFi for data & Windows XP; at the moment, the iPhone is currently stuck in iTunes "recovery mode".
Unfortunately, I never owned an iPhone before and certainly I haven't done a jailbreak (although I believe one is in my near future)
Unfortunately, I don't know the baseband version (because the iPhone 3G will not boot to the Springboard/Winterboard GUI).
I need advice on which general direction to proceed.
Here are relevant details:
How does this plan look so far?
Q: What would you suggest as my next steps to resolve this problem?

Unfortunately, I don't know the baseband version (because the iPhone 3G will not boot to the Springboard/Winterboard GUI).
I need advice on which general direction to proceed.
Here are relevant details:
- The jailbroken iPhone 3G iOS 4.2.1 has been working fine since August on T-Mobile
- The only 'problem' was that Cydia video apps apparently work best on iOS 3.1.3
- Suddenly, this weekend, the iPhone 3G locked itself into iTunes recovery mode
- I connected it to iTunes but stopped short when it wanted to install whatever iOS it wanted to install (I don't want to do the wrong update & later regret it)
- Doing research, I have come up with a tentative plan for recovery
- Would technically knowledgeable folks here please review my plan & offer advice?
- Recover the phone, if possible with all data & with the jailbroken iOS intact
- If that's not possible, at least recover the data & get the iPhone back on T-Mobile
- That may require 'unjailbreaking' or learning how to 'jailbreak' myself
- If possible, I would also like to downgrade to iOS 3.3.1
How does this plan look so far?
- Download the iOS 3.3.1 ipsw from iClarified
- Connect the iPhone to Windows XP iTunes via the USB cable
- Start the backup process & hope that the data backs up (it has never been backed up)
- Hold the shift key down to install the iOS 3.1.3 ipsw (somehow?)
- Once the iOS 3.1.3 is installed, I need to then figure out how to jailbreak it
- Presumably I use one of these WinXP jailbreak tools
- iOS 3.x, JailbreakMe jailbreak tool
- iOS 4.1 & 4.2.1 greenpois0n jailbreak tool
- iOS 4.1 limera1n jailbreak tool (Windows & Mac)
- iOS 4.3.3 pwnagetool Mac-only jailbreak tool
- iOS 4.3.1 Redsn0w 0.9.6rc9 jailbreak tool, Windows & Mac
- iOS 4.3.3 Sn0wbreeze 2.7 untethered jailbreak
- Or, maybe I can skip all that and just use an 'unjailbreak' tool?
- Would someone kindly advise me as to the next steps?
