No - there is a bit more that you need to do.

By doing any changes this voids the warranty, I recommed getting off the Telecom specific PHONE/PDA/CSC files. You need ROMS that people have developed to get the full potential. Your I9000T will run on steriods.

Let me know if you do, I will post the XDA forum run down. My phone is 1000% better!!!!!
