Ok, I don't know much about iPhone but this is not a good sign i Think.
I tried downgrade to 1.1.1 from 1.1.3 which I accidently update from 1.1.2, so I can install the third party apps. But, Icould't do it because everytime I down/upgrade for JB for Installer, I couldn't get any phone service.
Today, I use Ziphone several times to JB, I finally go the Jb and Installer on th iPhone. But the problem is....Wi-fi is not working property.
It can connet to the router but dose not working.
It is showing the wi-fi is connected in settings, but not working. So, I went to setting and found out I have unmatched.... FW1.1.3 with 04.02.13_G, I think.
Dose anyone knows how to fix it?
I use baseband updater from installer but getting error.(says "Main" something...)
Oh, last night I downgrade the bootloader and baseband from installer when I tried to Jb. I think that was th mistake.
Please help me on this.
Iphone week 51/ 1.1.2

your phone remain 1.1.2 baseband eventhough you run fw.1.1.3 and it will works just fine, nothing to worry but googlemap locating function wont work properly but use locateme or navizon will solve the problem!
Bootloader can only be downgrade by hardware methode, dont go downloading whatever you saw from installer if u dont know what it is for and how or you may end up with a brick phone! wifi not connected? may be thats because you messed up with bootloader? not sure about that part! try ZiPhone there may be a fix with that app.
