Hey all! Pretty much last year I won the phone for free, but wasn't able to upgrade due to our family plan and had to let the phone collect dust. Once we changed our plan a few months back, I was able to upgrade my phone. Being new to Android, I didn't know much about it. A friend has asked me if I had Angry Birds and told him I couldn't find it in Android Market (we both have/had iPod Touches). I also learned that I couldn't use my school's Wifi unless I had Android 2.1 and above. That's how I learned of upgrade Sprint/HTC had released. Can anyone fully explain to me why/benefits of upgrading other than getting some games/apps and being able to use my school's Wifi? Also, what exactly will I lose/what can I save to my computer or SD card? Thanks!
