Guys, I have been researching this for a while now but I have a few questions I was hoping you more experienced people can help me with. I have a 3G which I just replaced with a 4S. I figured it isn't worth much to sell it so I am just going to use it on airplane mode around the house as a net device/remote. I want to try JB it since it isn't my main device, it is on iOS 4.2.1 (8C148). 1. What is the best tool for JB the phone, there appear to be a few out there. What would you recommend? 2. What tools do you recommend for skinning it? 3. Are there any apps you would recommend for my intended use of the phone? i.e wireless sync app for iTunes, remote apps etc. 4. Are there any performance tweaks that can be made? to be honest going from iOS3 to 4 ruined the phone. 5. How easy is it to go back to iOS noe JB? 6. I see a lot of talk of base bands, I presume this is the Modem Firmware? Mine is 05.15.04 which does not appear to be supported by redsn0w.... Any help is appreciated.
