How to change ROM Easily

Answer is Mik's new-baseband-patch

In past if you wanted to install any Custom ROM after you flashed official 2.3.3, you had to use KDZ tool to go back to Official 2.2 to get the network working.

but now you can easily flash any custom ROM by recovery. and if you do not see network(as you won't) then flash new-baseband-patch and bingo now you have signal....

BTW If you face any GSM or DATA related Issue after flashing this patch then report this to mik not me........ :)
