2.1 might not fix every problem, but it's well worth the effort. What have you tried to get your computer to recognize the phone? Most of the problems seem to revolve around win7 64bit.

Obviously, if you don't have access to the update software you'll need to go to a store. You could go to sprints site and look for the nearest repair center but I would call first to make sure they can do the job (bad experience with the cl14 update)

I would suggest switching to 2.1, you'll like your phone much better. If your phone is getting hot while it is idle (no screen on), you likely have an app that is running in the background killing your battery. If you are adventurous and are not too worried about warranties, you can look to rooting the phone and/or putting customer kernels on it. They can fix and improve the phone in many ways. There will be a lot of options in the next couple of days. 2.1 is much better than 1.5, it is a night and day change in my opinion.

 

In Camera mode, when you tap the screen, it displays a touch slider + and - to zoom in and out. Can't find a zoom for video though (yet)

 

The camera is a little faster in 2.1. There is no zoom though, auto focus yes. Edit: it appears that it does have a zoom. Never noticed it before. The camera is generally better though. I cannot remember what the 1.5 camera was like, but I remember thinking the 2.1 was much better.
