Hi guys

I bought an unlocked phone and tried to jailbreak it following the guide on modmyi.com 101
when i launch the jailbreak application, at first everything goes well
then i pressed the home and off buttons for 25s
once i see the icons asking me to connect to itunes, i release it
Then it gets stuck on this screen:


Looking for iPhone...
Sending Files...

***If itunes is running, please close it.
*** Hold the power and home buttons for approximately 25s.
*** Release when the display says 'please connect to itunes'.

Sending more files...
Booting iPhone...

And thats it
Its supposed to take about a minute to finish but i waited about 5 mins and nothing happens
And i tried that 5 times, same thing

can someone help me to jailbreak my phone?

Thanks a lot
