Timmie you dont really need to be "technical" or a rocket scientist to install an new OS on your phone... The most important thing you need is free time, some basic reading comprehension and willing to sacrifice your phone s warranty and risk bricking your phone.
My advice is not to go with the ICS upgrades yet. There are some really good GB updates that allthough they are not "complete" they are fine for everyday use and functional.
Spend sometime reading the threads, especially the ones for "Newbies", use google to familiarize yourself with terms like ROM, Kernel, Bootloader, Root etc and you are good to go.
Keep in mind that these people are developing on their own time, and should never be held responsible if you damage your device. Every device is different even if they have the same model number.
If you feel brave enough please go ahead and I promise you it s a lot of fun. Make sure you read VERY carefully the requirements and follow the instructions. Advantages and disadvantages exist in every OS, independently if it s "Official" or not. So far the worst ROM I used was the stock GB.
Good luck!
