I am a new android user. I had the 3G when it came out but i ended up selling it a few months ago. I just had a few Q's about some things on the hero. How can i get the apps to go into my SD card when i DL them from the market. Or do i need to do a root first. [which isn't out yet] Does a class 4 and class 6 make a huge diff in the phone. I have a 8gB class 4 in there right now and I was planning on buying a 16gB class 6 from new egg for like 20 bucks. Is there an app to make the font bigger other then spare parts., because i know it doesn't work with any of the apps on the phone.
