Wow- the iPhone 4 is really fast. I have both the EVO 4G on trial (since launch day so I have had plenty of time to see trends) and the iPhone 4. We're in a Sprint market with 4G and with AT&T having the newer HSDPA. On the iphone 4 I am getting up to 5.1 MB/s in many instances and usually never less than 2.5 MB/s even on launch day at night with everyone on. By contrast, I've had the EVO two weeks now. The Sprint 4G is highly variable in speed, often being 1.5 MB/s or less. While it sometimes can get to 3 or 4 this is rare and its usually not more than 2 MB. Plus, the speed varies dramatically in the span of a few minutes so it is not stable, whereas the AT&T speed is very stable. Finally, driving around town the Sprint 4G speeds vary dramatically, from nearly 0 to fast, but very unpredictable. On 3G, Sprint 3 here rarely gets above 1.2 MB and is often at 0.6 to 0.8 MB/s- lousy. Conclusion- At least in Charlotte, NC the Sprint 4G is not really reliable, not really 4G most of the time, and often actually achieving typical 3G or less speeds. AT&T meanwhile, has really turned up the juice and is very, very fast, often at 4G types of speeds. Any other experiences elsewhere?
