Just to keep you informed.
Updated to Ver3 bootloader using Blackthund3r's NV500.exe app. Went smooth and no issues. Note: I wa already on Ver2 of the hacked bootloader, so I didn't have to do the whole process as in Civato's thread;
Several options you can use.
Repacked Rom, removed 500remounter, packed tweaked kernel @civato, currently testing for SOD and 3g. Wifi, 3g, and GPS function normally.
Added EC Rom back to the package. (I don't see a difference)
Perm /System R-W works great.
Also, currently chasing down the Maps update signature error (probably my fault). Not sure which package Maps come from on install, but will eventually find it.
Other than that, when finished will post a new version for Ver3 bootloader.
Edit: 3g still drops off. Use wakelock
