I'm a bit of a n00b to this area. I just got a Samsung Intensity II u460 phone and I'm looking at what I can do in terms of hacking/modding. I'm not interested in switching the provider of the phone, (which in my case is Verizon), so I might not need to bother trying to unlock the phone unless I need to do that to do any software mods. I'm mainly interested in using my own mp3s as ringtones, custom skins, and whatever custom software/homebrew apps I might be able to use on the phone. I've also read there's a way allow my phone to use my Wifi for internet.

I would greatly appreciate someone pointing me in the right direction on this. I'm not looking to do anything particularly shady, (at least I don't think so...)
