My Christmas gift this year... the HTC Hero. Quite happy so far. However because neither my hubby (he has a Palm Pre) and I have ever had an android before, I have a few questions that he can't seem to answer. So please excuse the simiplicity of my questions 1)) What is the best way to maintain good battery life? Is there a specific % I should never let the batter fall below? 2)) Besides from being able to pull ringtones from my MP3 files on my PC, are there any good websites that offer free ringtones for android devices? 3)) My Hero came packed with a whole bunch of apps that I will never use. Like NFL Mobile, Nascar, Amazon and YouTube apps. Is it okay to delete these from my phone entirely? Will doing so free up memory for bigger and/or better apps? 4)) Are there any types files or apps that I should not put on my phone? Thanks for your help!
