Please forgive these very basic questions. I'm new to smartphones and considering the Eris. If I purchase my Eris now w/OS 1.5 (Verizon), will it receive the 2.0 upgrade or do you get what you buy and that's it? If my Eris will upgrade to the 2.0, will that OS allow some of the same apps you can get on the Motorola Droid like the one that allows you to point at the sky and it will tell you the constellations, etc? Thank you for your patience and assistance with the newbie!
