iPhone dead, HELP!

[twowheelesonly]

I installed 4.1 on my 3G a few days ago, jailbroke it, unlocked it with yellowsn0w. Today, I tried to install mobile terminal and it didn't work with 4.1. After I tried to remove it in Cydia, it crashed on me and was stuck on the apple logo screen.

I should I do to bring my phone up? Hope you guys can help me.

Thanks

leave it at the apple for while, maybe it will rebot by itself a few times, then maybe work. If not you must restore with itunes, preferably with a pwnd firmware.

Restore it to 4.1 (I'm assuming you have your SHSHs if you just recently updated it a few days ago to 4.1) and jb it again. If you want mobileterminal, add source podzombie.com/repository and get the iOS 4 version. If you want to unlock, you should probably be using Ultrasn0w...yellowsn0w is quite outdated.

iTunes can't even detect the devise. the apple logo screen flashes every few seconds. I don't think I am able to turn off/turn on the iPhone. It just stays in this state. is there anything I can do?

Thanks for help

youll have to do a hard reset (home+power until it shuts down) then use DFU mode to restore.
