Flash a ROM. Customize it to fit you. And have fun overclocking and undervolting if you wish.
Right now I on Das BAMF sense 3.0 RC4.9 on the imoseyon 3.4.0 kernel. Clocked at stock speeds but overclock to 1.6ghz every now and then. Highly recommend it for a very stable, fast, smooth, sense 3.0/gingerbread ROM. Synergy is also a good ROM as well if you like sense.
Enjoy the flashing (be careful though), overclocking, tethering, customization, and freedom of root
