Apple made mention that some developers, when updating to iPhone 3.0 Beta 5, might experience problems connecting to AT&T’s data network. Apple asked any devs so affected to contact them, and one dev who had the problem called in and let us know what Apple told him:
Apple just called me back, had me turn the phone off then back on. Then turn the wifi off and try it and it seems to be back to working. Thaaaank you apple.
Thanks indeed! If you’re experiencing similar problems, you might want to try the above. If that doesn’t work for you, however, get on the phone with Apple asap.
(Thanks Josh for the tip!)

Despite the iPhone’s Mobile Safari browser rendering pages faster on Edge than many “competing” devices can on lesser browsers with faster connections, the race to speed the feeds continues, and AT&T has not only taken an early lead, but is positively driving towards the 3G finish-line.
Amazing what a little technology (and a billion dollars) can do.
WMExperts.com cites a recent survey where AT&T’s HSDPA trounced EVDO Rev A., averaging 755kbps with bursts peaking at 1.6mbps(!)
In Apple-parlance: It’s a screamer.
But wait, there’s more: AT&T intends to increase its network speed by a factor of 5 by next year. That’s a quintuple screamer right there, never mind the upcoming switch to 4G LTE speeds…
