I just tested my iphone 3G speed on Thursday, and again today, at various spots, and found the speed of ATT's HSPA+ network has "mysteriously" increased from a steady 1.2 Mbps download/.32 Mbps upload speed to between 3 and 4.3 Mbps download/.54 to 1.2 Mbps upload speed.
How CONVENIENT for ATT to suddenly unlock the speed that has probably been there all along, so they can boast that their so-called 4G network (HSPA+ actually) can compete with Verizon's upcoming 4G LTE network.
Makes me furious that they could have done this earlier, which will no doubt come out in the news next week as a smarmy way of keeping iPhone users from defecting, or to keep new users from going to Verizon.
Both ATT and Verizon are deceptive companies who will do anything to make their bottom line - what's that you say? --- "I'm SHOCKED, SHOCKED" (with apologies to Capt Renault (Claude Rains) from Casablanca).
