So recently I was given an iphone, but I have t-mobile so it needs to be jailbroken. Its a 3g and has FW 4.1 on it. I ended up downgrading from 4.1 to 4.0.1, because with the use of tiny umbrella, I found that the 4.0.1 SHSH files were saved. Long story short, I was able to downgrade and currently have 4.0.1 FW on the iphone. Whenever I go to jailbreakme.com it recognizes that my phone can be jailbroken and allows me to slide the bar. Once i slide the bar everything goes away and it sits there on the purple screen. I cleared my cache, history,and cookies, and restarted my phone, but the same thing happens. Can anyone help me with this????
