T-Mobile Calling for Help with 4G Push

I hope everyone knows that the "G" in front of the number means "Generation" and its mostly about the speed of data transfer. If you need your handheld to transfer any data faster than 10mbps (and you're not going to see that on a handheld), you have issues. If you have a laptop, note/netbook, then you might need it up to 20mbps. I have FIOS at my house running at 20mbps and its plenty fast to do anything I want. The reason that T-Mobile is continuing to rollout the HSPA+ is because its backwards compatable and you dont have to pay extra per month or buy new 3G handsets. HSPA+ is capable of throughput to 21mbps! Do you really need to go faster then that on your phone or laptop?
