Hey guys. I currently have an iPhone 3G running on version 3.1.2 with firmwire 04.26.08. I wanted to upgrade to 3.1.3 since MobileMe app requires it but a friend of mine upgraded to 4.0 on her jailbroken/unlocked 3G and she has yet to experience any crashing or slow down issues.
I have been using these guides to update: http://www.ihackintosh.com/2010/02/jailbreak-iphone-3g-3gs-os-3-1-3-with-pwnage-tool-mac/
My question is if I decide to try out iOS4 using jailbreakme.com on my 3G and decide it has caused my phone to slow down or crash will I be able to downgrade to 3.1.3 without loosing my jailbreak/unlock by using the guide above? (I'm using T-Mobile)
Sorry if this seems like a dumb question or repetitive. Honestly I have only updated once and I am moderately incompetent when it comes to this technical type stuff haha
I guess really what I am trying to get at is there a way I can upgrade to OS4 without loosing my 04.26.08 firmwire and also be able to downgrade back to 3.1.3 if I decide I dislike OS 4..?
