With my jb iPhone, I can customize my wallpaper and use some different app icons. I can run apps like qTweeter and SBSettings to make my life easier. I also have GV Mobile!
Why would anyone NOT jailbreak?
how did u get google voice mobile on your iphone...i tried to via safari and it said it is not supported
I have jailbroken my phone in the past, didn't find any real use out of it. The only think I liked was the fact that I could change my wallpaper, but that's it. I found that I spent more time tweaking and tweaking than actually using the phone for it's only real purpose, which is making phone calls.
