Answer for those asking if this will work on there Droid phones... NO it will not. Also this hack does nothing for Sprint users because throtting is done server side, not client side on your phone. Plus the zip file will ONLY install correctly on the file system it was based on. Therefore the zip will cause infinite boot loops if you flash this on a different system than what it is made for.
If you really must know for yourself that this hack does/doesn't work, flash myn's newest RLS 5 Rom and he has this hack as a separate zip download on his Rom thread. This hack only works on the system it was based from. Unless you manually make the edits yourself on your current system. Still this does nothing for Sprint users. And I seriously doubt it will on Verizon either. Initially this throtting hack was effective on gsm networks, not cdma.
