I take it, then, that this eBay listing, VERIZON-BLACKBERRY-STORM2-9550-UNLOCKED-STORM-2-9520
is a bit misleading. I sent a message to the seller, asking which is it, 9550 or 9520. He replied that it's his understanding that they are "the same, when unlocked". But my understanding from this thread is that getting this Storm 2 to work on T-Mobile will be tricky, and some of the apps I use will cause it to fall off the EDGE.
