Screaming Penguin - Source Does Matter

I will be buying a new phone soon (the old employer's BlackBerry is going away) and have been looking at getting an iPhone. I am a notorious hardware holdout, rather than an edge cutter (I like the 2 gens ago chips, they are fast *and* cheap - still typing this on a MacBook core duo I got a few years back, still works fine). That, combined with the fact that the company decided for me in the past, is the reason I don't have an iPhone already.

Yet, the time has come for me to get a new personal/work mobile phone. So, I put the question to the current iPhone owners that frequent the TotSP bitwaves, how's your iPhone treating you - still think it's the greatest thing since your first beeper?

I was a bit dismayed originally by the lack of third party app support - but that's resolved now (though it will take some time for apps to trickle into actual usage). I was also concerned about not having a GPS - despite what a lot folks say that will do to battery life (the GPS on my BlackBerry is one of the most used features, frankly), and it looks like that may get resolved in June with a new 3G/GPS iPhone too.

Other than those concerns, how do the rest of your experiences with it stack up. How does it work as a phone in real life? How handy is the WIFI (the EDGE crap on the BlackBerry drives me nuts)? How has your "service" been with AT&T (I have them now, so no surprises for me, just curious what iPhoners think).

I will likely wait at least to find out what happens in June, would be great to get the 3G/GPS one if it drops - but my choice is still $400 bucks or so for iPhone vs free for just about any other device in the AT&T store at the same 2yr contract lock (I have had Cingular/AT&T for 6 years or so, so as much as I despise the contract thing, it works for me because I will likely have them for another 2 years anyway, and it gets me free/reduced hardware other than the iPhone).

What to do, keep taking the free (as in contract free) junk, or grow up and get an iPhone?
