Welcome aboard!

After its initial full charge, use it until you get a "low" warning a couple of times, charging fully after each. That will help condition the cells, after which you can top it up every day or so depending on use. In general don't run the battery right down in regular use - ~30% or so is considered a safe minimum to prolong life.

I'll pass on this one. I'm olde skool and hate musical ringtones.

I don't believe it's ordinarily possible to delete these, but I suggest you check with the folks over at the Sprint Hero forum for confirmation and any workarounds. From that list of apps I'm assuming yours is a Sprint device, anyway?

Not that I'm aware of. I use mine like a USB thumbdrive so it contains quite a few files that it can't even read!

 

2) Try this one HTC - HTC e-Club

 

For #2, there is an app, called mobilo or something, that has plenty of free ringtones (just search ringtones on the market)
