Hi Everyone, This is my first iPod that I've ever own and I'm loving every bit of it. I have a few questions that I need help with, 1. Is there any App that allows you to change the "Black Background" on the 2nd Gen Touch v2.2 or is there any other way to change it. 2. All My current Music is in mp3 format, what other format would you guys suggest converting to w/ better sound quailty but doesn't kill the space. I only have 8GB. Also what bitrate should I use w/ the new format. 3. Does anyone have any experiance with the Sennheiser CX-500 In-Ear Headphones... ADDED 4. Is there an App that lets you play other Video Format like avi, Xvid etc.... or is there any other way to play those video file... I guess thats all for now, Thanks.
