So I got a fascinate last weekend, lov'n it (first android).
Rooted it last night, which was a little scary. It all worked. I got the Superclean v2.8 on it, and I love the debloat. The all in one link process using Odin was dead easy. Only problem I had was that my desktop stopped recognizing the phone when it booted to download mode, had to use my laptop.
Only issue I'm running into is that some programs don't connect well. For instance, I use Medscape ( a drug reference app) for work, and it won't connect to download new stuff on either 3g or wifi.
Also, the app market won't run on the wifi, but will on 3g.
The wifi works when I'm just browsing the internet, or even downloading apps that I picked on the pc. It is perplexing.
