iLiberty: Easy to use Application to JailBreak, Activate and Unlock iPhone

Hi guys I have quick question on ilibertyX for mac can I jailbreak my 3g 3.0 iphone using ilibertyX do I have downgrade ? I'm assuming I have to downgrade to 1.1.4 or just go ahead and redsn0w, Another question is I am having a problem with wifi on my iphone it is not connecting can ilibertyX correct this problen I saw a download on the payload that says reflash/edge/wifi/bluetooth, i have another iphone that is jailbroken already I would like to know if this can fix the problem using this download before I proceed.

I WAS WONDERING CAN I STILL USE THIS SOFTWARE TO ACTIVATE MY IPHONE OS 3.0 DON'T NEED TO JAILBREAK IT AS ALREADY HAVE DONE WITH REDSNOW NEED A QUICK REPLY

Thank God for the guy who created iLiberty..2 months w/o my iphone,and in 3 minutes its fixed..im so grateful!

I restored my iphone 3G when I shouldnt have as i live outside the UK and the US. I bought it in the UK and I live in asia. It was then on recovery mode..the one with the USB and itunes icon connecting and i could only make emergency calls. I then blackra1n it and finally it works! wifi is ok.. only problem is my sim card is invalid. how do i unlock the sim card?? it shows 'No Service' pleeease please help!

my iphone 5 is locked thru iCloud. my boyfriend and i got phones together, we broke up and he disabled it. i have been searching EVERYWHERE to try and find a way to bypass this firmware lock (i think it is a firmware lock at least!?!?!) I'm new to this whole apple thing, any suggestions or ideas? please help thanks lindsayo91@gmail.com
