I really want to root my phone, but I have a couple concerns/questions. 1. Is rooting actually as complicated/hard as it looks? 2. The thing I read somewhere about sandisk memory card not working.. is this accurate? 3. If I mess up, is it hard to fix? and finally 4. What are ROMS? (I'm a noob, cut me slack) Any input from experienced Android users would be greatly appreciated!
