Hm. Kholi... now you're making me think I should have exchanged my 3G... ugh.
There's no REAL reason to do so unless you're always on your phone. Mines is always with me, I'm always on the net or checking email, texting and during all of that it's playing music in my ears.
So, I'd like to not have to worry about slow-down while I'm plugging Zombies (ZombieVille USA) and listening to Silversun Pickups. xD
