I recently acquired a HTC Eris from my friend who upgraded to an iPhone. I am an Android newbie but pretty tech savvy. What version of Android should I install or should I just stick with 2.1? Should I install a custom rom? I want to be able to play around, but value stability. When I used the reset/wipe procedure, i.e Volume Down, Send, Power. Did it reinstall the image of the OS or did it just wipe personal data? I am wondering because I have the left scroll ball problem and some other glitches and crashes.
