In side by side comparison of EDGE and Wifi browsing on the T-Mobile’s new Blackberry 8320, The Boy Genius reports that EDGE is faster than wifi. That’s a big disappointment; interesting to see where the bottleneck lies and whether it can be improved by a software upgrade. The new 8320 also does not offer GPS; I think I’ll definite hold out for the 8820. Despite the disappointing Wifi throughput, I am still interested by the ability of the new Blackberries to support unlimited flat-rate voice calling over Wifi, since I’m often near a wifi connection at home, work, or a Starbucks.
