Apple's iPhone: The Future is Here

Battery Life
Using the iPhone you already know it's not going to last very long on battery; I didn't have enough time to run the full suite of battery tests, but those that I did run will give you a good idea of what to expect.
The first test is a strict email benchmark. I created a gmail address and signed up to receive all of the latest postings from some of the most popular newsgroups through Google Groups via email. The end result is a mailbox that gets over 5000 messages a day, and a perfect worst case scenario email test.
All three devices were run on the Edge network to be the most balanced, but keep in mind that the Blackjack supports 3G and the iPhone can run over WiFi. Bluetooth was enabled during the test, but remained unpaired with any devices.
The Blackberry Curve was the only device out of the three that could receive emails instantly, and it did so much faster than either the Blackjack or the iPhone. Both the Blackjack and iPhone automatically checked the mailbox at 15 minute intervals, but in actual email download speed the iPhone was clearly faster than the Blackjack.
Battery life for email was a clear victory for the Curve, lasting just over a full day doing nothing but checking emails. Keep in mind that all three devices were set to their silent profiles, meaning that the Blackberry was constantly vibrating as it received multiple emails each minute.
The iPhone more than measured up to Apple's own estimated 6 hour battery life during Internet use, lasting 6 hours and 53 minutes. The Blackjack on its standard battery came in last at a bit over 5 hours. From our experience, the extended battery would probably bring the Blackjack up to the iPhone's battery life.
It's important to note that these tests are best case scenario as I'm not walking around town with the phones while testing them, which would be far more stressful on battery life. That being said, the Blackjack and iPhone simply don't cut it for high volume email devices, there's just no replacing the Blackberry. For casual email though, either will work fine.
Our other battery life test is strictly web surfing; we loaded a series of nine web pages stored on a local server and looped the test until the batteries ran down. The screen was left enabled on the Blackjack and iPhone but we couldn't force the Curve to do the same, so its results are slightly inflated by having a screen that went to sleep after the first 30 seconds of use.
This time on WiFi, the iPhone comes in closer to its estimated 6 hour internet battery life. Again, you're looking at best case scenario battery life; watching a lot of videos on YouTube will run the battery down

If there is no GPS hardware built into a device, 3rd party software won't help. You have to have the hardware receiver built in.

Fortunetly by law every new phone activated as of 2005 must have built in GPS for E-911.. Just one small baby step from there repurposes that GPS for coolness... My i720 allows this.strikeback03 - Thursday, July 5, 2007 - link
Doesn't the law simply require the carrier to be able to determine the location of the phone, but not specify how? Allowing the carriers to determine by distance to cell towers instead of GPS?Locutus465 - Thursday, July 5, 2007 - link
I beleive GPS is required... At least this is what I was told by a Verizon rep that refused to activate an older phone I had.Cygni - Thursday, July 5, 2007 - link
GPS is not required by law, yet. Location support IS required, but is already present on nearly every phone made in the last 3 years.plinden - Tuesday, July 3, 2007 - link
Leo Laporte in one of his podcasts this weekend mentioned that he heard there is an SDK for the iPhone that's ready for OS X but not Windows, but Apple (ie Jobs) wants to release both versions at the same time, hence the delay.
That's just a rumor, but it's almost certain there'll be an SDK at some point, although it's extremely likely, if not certain, that developers will have to go through Apple to get their apps published to the iPhone (ie via iTunes).
Give it six months, like I'm doing. I'll likely get the 16GB version with 3G when it's available.

There will need to be good 3rd party support for me to even consider it. There'll also need to be a good (and inexpensive) all in one chat client. And Mahjoong, that's totally a requirement.sviola - Tuesday, July 3, 2007 - link
You should check the Nokia N95, it has the built-in GPS, altough it runs Symbian OS.Locutus465 - Tuesday, July 3, 2007 - link
Well yes, my phone has built in GPS hardware as well (as do all phone inc. iPhone). It's just missing the app + maps (unless you're sayind the nokia comes with software + maps which would be the bomb). So I would just need that part of the equation. As a matter of fact the Samsung i720 also allows you to use the phone as a plain old GPS device, so really if I wanted to I could potentially blue tooth it to a laptop for instance and go that route.Locutus465 - Tuesday, July 3, 2007 - link
Oh yeah, on the i720 to set an MP3 as your ring tone you just need to browse to it in flie explorer, tap and hold ("right click" in Windows Mobile) and select "Set as ringtone" :)Automatically copies to \Windows\Rings and sets the song as your ringtone :D
