Hi, I'm an iPhone user just trying our Android for the first time. I bought a "Samsung Galaxy 3" today. The specifications at gsmarena for this phone also mentions that it is "upgradeable to v2.2". I wonder where and how can I install the froyo update? Also, what is 'rooting' and is it possible on this phone? Some details about my phone: Model Number: GT-I5801 Firmware Version: 2.1-update1 Kernel Version: 2.6.29 root@SE-5604 #2 Build Number: ECLAIR.DDJG6 Many thanks for your help!
