I was an iPhone owner for 3 years (owned and used every version produced), and recently made the switch to Verizon and to the Motorola Droid. I was able to transition to the Android OS pretty easily, as I am somewhat technologically savvy.
However, I'm sure there are things that I won't be able to figure out on my own. First and foremost I'm looking for tips/advice on customization (wallpapers, widgets, themes, skins etc), and any helpful apps that may fly under the radar in the Marketplace.
I already love my Droid, and have no regrets from selling my iPhone 3GS, but know there is more for me to learn to make my Droid experience truly awesome.
I look forward to hearing your opinions, advice, and input on any questions I think of.
