I have the SAME one. I have a problem though, my phone only vibrates and it acts as in headphone mode no matter what, except when I got to Music and I press the blackberry button and switch to Speaker Mode and I'm able to hear and if I leave it on, I'm able to hear the tone of the keypad when I dial and the ringtone when people call me. As soon as I exit, it goes to headphone mode :/ I feel like an intense noob lol. I've been using iOS too much.
Sorry its my mistake Miera, there are two tweaks that are 90% similar. One called Move Lockscreen to Unlock and one called Move2Unlock. I didnt know move to unlock existed so I thought it was the tweak I knew. We are all human and make mistakes.
Since I seem to have similar theme interests as you, what are some nice HD themes? Just jailbroke my iPod, 4.2.3, and now I am in need of some good ol' themes. ;)
