I want to upgrade this to 2.3 or 3.0. on my Galaxy S phone, the upgrade process is simple (settings, about, system updates). I dont need a legit release, just a stable one. any ideas how to get to that or which one to use? I also was curious if I could pair my BT headset and make voip calls. I dont need to receive calls just make them (local US) - is there a decent app for that without having to pay a monthly fee or buy minutes? how about an app to get to my shared windows drives that store media and docs. I would like to be able to map a network drive. Thanks for helping a rookie out in advance!
