Considering a cell phone upgrade? Maybe you should wait a few months. The BlackBerry Thunder 9500 (RIMM) will hit shelves this fall, available exclusively to Verizon (VZ) customers in the U.S. and Vodaphone in Europe. With a touchscreen capable of running on worldwide networks, if the Thunder is well executed it could give the iPhone (AAPL) a run for its money. But, rabid Apple fans, don't fear. Steve Jobs is expected to unveil a new 3G iPhone in early June, featuring a significant boost in speed and storage capacity.
