Guys, i wanna ask you something. I have a Samsung GT-I5500 that works with Android OS 2.1. Can i upgrade the version of Android to 2.4 and if yes how? Understand that i'm new in Android OS and totally noob And, if i decide to upgrade my telephone (if possible), can i have problems such as lost of signal (for network) and other things like that. Thanks indeed. P.S. Can i do that with Samsung Kies, if yes how?
