I have a samsung captivate (AKA galaxy S) SHG-I897. Been watching a lot of youtube videos and got it rooted and learned how to put it in download mode and how to use odin. But this isn't really about that phone itself. Cause this would really apply to any phone that one might consider updating. The phone came with 2.1. When 2.2 came out I got that, and then here lately 2.3.5 became available through samsung's KIES update program for the PC. But my question is.. is there even a reason for me to just go on and on updating? I know that I can update 2.3.5 to 2.3.7 (even though I don't know where to find the files to use in Odin) but what is the difference? I don't seem to notice any real improvement. My phone has not gotten any faster. I haven't noticed any real new functionality out of all these updates, over the years. Unlike with windows, which needs constant updates just to stay alive. The best gains I've seen with my phone have been through apps that I've downloaded, such as Titanium backup and Adfree and Angry Birds. So why should I even bother to upgrade to 2.3.7 or 4.0? What do I stand to gain?
