Hello Guys, Well I bought my Galaxy here in India yesterday, and you all and this forum has been a major source of info to make up my mind Thanks to you Well I've bee browsing this forum trying to understand all that I need to know for the past two days before I could muster the courage to ask a couple of questions. 1) My Galaxy is on Firmware II3, is it worth upgrading to IK5 ? 2) When I upgrade, does everything, contact, apps etc, get wiped of from the device or do they remain as they are ? 3) Is there a way I can take a complete backup of my contacts, apps etc and restore them after a firmware update ? My phone has not been rooted yet and I plan to use ODIN for updating the firmware.
