I have an Unlocked and Jailbroken iPhone 3G for T-Mobile. Currently I have 3.0 installed with 4.26.08 firmware. I'm wondering what is the best (fastest?) software to jailbreak and unlock this phone with? I would like to reformat it completely and start new since it has begun to be quite slow. The reason I ask is because I have heard that 4.0 on the 3g makes it very slow. If you could help me by also telling me which unlocker to use or even a guide how to go about doing this it would be much appreciated! I have been trying to figure out what I should reformat it with and have gotten lost since it has been so long since I upgraded to 3.0. If you guys could point me in the right direction that would be great!
