Hi, I am the newbie here and I need some help.This is my first time using Android OS. My wife's phone is Samsung i5801 Apollo which is using Eclair 2.1 can I upgrade to Gingerbread or I have to get Froyo first? Her phone is unlocked and our carrier is AT&T we don't have no data plan other than using free WI-FI like, at home. Can some one help me answer this is possible to do? Thanks in advance.
