Do you mean 8530? That's what Verizon has.
I actually did that move, it was much better as my S1 was dying.
You will notice the difference, I would wait for the 9650 but if you really want the 8530 then go for it!
Okay, well now that I know your carrier.....
The 8520 is a good choice, basically any new device besides the Tour is good!
Yeah, I mainly just wanna make the switch because of the extra app memory and wifi in the 8520 but i love everything else about the storm especially the big screen. I think ill just get the 8520 for now and upgrade to the storm3 when it comes out
