No Wi-Fi or Signal?

Follow this guide to re-flash your phone with the baseband that came with 1.1.2, then use DFU restore to 1.1.4. This will give you a clean baseband for 1.1.4 and get rid of those pesky Wi-Fi and signal problems.
NOTE: You will lose Wi-Fi during this process, so Install Term-VT100 app on your phone with Installer or iBrickr so you can perform these commands from the phone itself.
1. Make sure Auto-Lock is set to Never by going to Settings -> General -> About
2. Download the BB tools package with the bbupdater flasher and the required baseband files. You will be using ieraser for 3.9, not ienew.
3. Upload the files (bbupdater, ieraser, secpack, ICE04.02.13_G.eep, ICE04.02.13_G.fls) to the iPhone via SFTP or SCP to /usr/bin
4. SSH into the iPhone and make bbupdater and ieraser executable,
chmod +x bbupdater and chmod +x ieraser
5. Disable the CommCenter with the command:
launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
6. Open Term-VT100 on the phone and go to /usr/bin
7. Erase the baseband with ieraser
./ieraser
8. Flash the 4.02.13 baseband onto the phone
./bbupdater -f ICE04.02.13_G.fls -e ICE04.02.13_G.eep
9. After 3 minutes the baseband is programmed. Check by typing
./bbupdater -v
Verify that the output has the new baseband firmware version as shown below
firmware: DEV_ICE_MODEM_04.02.13_G
eep Version: EEP_VERSION: 208
eep revision: EEP_REVISION: 1
bootloader: BOOTLOADER_VERSION: 3.9_M3S2
10. Put phone in DFU and run iPlus to unlock
11. After running iPlus, you can check your baseband and bootloader with BB Info. See Determining your Bootloader with BB Info, from Installer in the Guides. 3.9 Fake Blank is for 4.6 phones only. For phones that have the 3.9 bootloader, there is no bootloader change.
