Question [Q] Toggle 2g on stock rom?

I installed Toggle 2g on cm7 rom, and it worked pretty well, changing into 2g mode after 5/10/30..mins of standby. Great app in my opinion that saves a lot of battery. It uses Injection. Now i got back to stock rom and wanted to ask, if someone could make a version working on stock. There is some instructions on the thread, but i didnt have success..
