Yes. Oh yes.
Now that’s an interesting idea.
It has a three-axis accelerometer built in. So far, the most useful application of it that I’ve seen is iPint, linked above.
(There are also cool games and stuff, plus some apps automatically reorient themselves to portrait mode when you rotate the phone.)
Figaro:
Which Hold 'Em app is this, exactly? And how’s the AI?
Also, two stupid questions for people regarding apps (some of the iPhone functionality isn’t intuitive to me):
(1) If you pay for an app, is that a one-time fee, or is it monthly? I assume it’s the former, but I want to make sure.
(2) Is there any way to rearrange your apps to pick which ones go on the first page of your home screen by default?
Thanks for all the suggestions, everybody. This has been really helpful.
It has accelerometers in it, but I have no idea how the technology works, only that it does. 
You press one till it wiggles, then you can move them around.
…Boy, to be Michael Scott right now.
It’s the one that’s currently #13 in the top 25 paid apps on the application store. It’s by Apple. The AI is good enough that you can’t win if you play loosely and make bad calls, but it isn’t very good in heads-up play. Also, every now and then the computer players will do illogical things – like call large bets that put them all in when they have no hand, etc. The best part of the game is the interface. If you hold the device long-ways you get a table-top view that allows you to muck your cards with the flick of a finger and bet or check with just a tap. (I can’t stand the view you get when you hold the phone/pod upright. You have to watch avatars “play” each hand at the table, and it takes forever.)
I’m a decent player who can usually break even or better in a cash game, and I’ve been very entertained by it.
Your assumption is right. Once you’ve paid you have permanent rights to use the program and you get free updates when they’re released. This second part is important because most of the programs I’ve downloaded have been upgraded at least once since. The app store automatically alerts you that updates are available for programs on your phone/pod.
Thanks for the response, Figaro; this is good to hear.
As for poker, I think I might try out the THETA Poker app. From the reviews, it looks like it might have a more sophisticated AI than the Apple program does, although the graphics are worse. I’ll let you know how it plays.
iRetroPhone-- Adds a rotary dial to your iPhone!
AutoMangle–If you were a fan if the Car Wars game or Carmageddon, you’ll like this.
33 posts and no mention of Trism? Trism is a really nice game – you keep moving triangular tiles around, trying to match three or more of the same color, which makes them disappear. And be replaced by more tiles. Good, lightweight game, except when the explosive tiles explode…
Trism and Wurdle probably represent 2/3 of my iPhone usage.
Freeware that I like (and they’re free, so just try them out):
myLite / Pandora / AOL Radio / WeatherBug / Stanza / iSaber / Trulia / midomi / iWant / AstroTilt
1Password is a freeware version of 1Password for the Mac; it can be used as a standalone program, and since iPhone Apps can contain instances of web browsers (it takes something like 10 lines of code to do this), 1Password can save your username and passwords for web sites and you can access them right there. This addresses the issue of data entry being slow on the iPhone, since you don’t have to (a) remember your username and passwords and (b) have to type them in. The author also makes the 1Password (Mac) shareware program, and is trustworthy (or, at least, has many customers and has developed security apps for several years). The good thing: if you have the shareware version for your Mac, it can wirelessly sync with the 1Password on your phone, keeping all of your passwords safe. Again, this guy encrypts everything everywhere, and reading through is website and the forums, he long ago proved that he knows how to protect information.
**Shareware already mentioned:
AirSharing
More Free Apps:
Bloomberg** tracks stock prices and business news, and you can configure it with your stock portfolio, so you can drive down the street, have it update, see your 401K’s loss of the day and decide to drive off the nearest cliff.
TapTap revolution – guitar-hero/DDR game. Free, but it makes my iPhone run HOT; probably best to play this when you’re plugged into a power source.
Low cost programs (honestly, is a $12 astronomy program going to break you?)
PocketPedia is a freeware app that you can use to keep a catalog of your DVDs, books, CDs, etc. It is really cool to be able to swipe through my list of (2400+) DVDs (it has a cover-flow list which is really, really cool). By itself, it might be cumbersome to enter all of that info, but I bought their shareware Mac app DVDPedia, which can create “smart lists,” wherein I can define all sorts of subsets (e.g., DVDs purchased in the last two weeks, DVDs starring Bill Pullman between 1999 and 2003, DVDs I’m planning to buy, etc.). In reality, I think PocketPedia is offered for free to whet your appetite for the shareware programs on the Mac, but you get an awful lot of functionality for that price (since they wirelessly sync with PocketPedia).
TymeLinz ($1-$3?) makes countdown timers for any number of upcoming events, counting down in any mixture of years, months, weeks, days, hours, minutes and seconds, and also does the opposite – counts time since events occurred.
Grocery Gadget – one of the million shopping checklist apps out there, (and I seem to have bought them all). This one just seems easier to use. It comes with a pre-made list of items to buy, and you can add your own. The thing with these list managers is that data input is a little slow because it requires typing, but if you can just swipe your way through lists, it’s easier. You can also take photos of the items you want to buy and can calculate a running-total of what you’ve purchased. Years of shopping have left me with an awesome ability to recognize products merely by reading their names, so the photo thing is not important to me (yet).
Astonomy Apps. So far, I have IAstonomica, Uranus and GoSkyWatch Planetarium. Only if you really care, because they’re about $10 each. iAstonomica & Uranus are better than GoSkyWatch, but there was some reason that GoSkyWatch was also good; I just can’t remember it off-hand.
VelaClock – graphical time display of clocks anywhere in the world; the displays also show textual info (sunrise, sunset), and the graphics show night, twilight, daytime, etc. All of these are correct for each city’s lat/long positions. I don’t seriously think anyone else has a fascination with sunrise and sunset at cities around the world, but if you’re me, it’s a cool program.
Alimony: I think this cost one or two dollars, and I love it, even though I’ve never been married or divorced. It shows a ticking countdown of “time until you can stop paying alimony” and a ticking “alimony you’ve paid” or alimony you still have yet to pay. But I use the app to tell me the time until my early retirement (8 years, four months, 18 days) and my total pay for the year (down to tenths of a cent!), all updated once per second. I think the author may have some issues with his divorce, but it’s useful for my purposes as well.
Ultimate Wonderful Calendar and Appointment Manager: Doesn’t exist yet. (I’m working on it).
On rereading this post, I wonder how many people are obsessed with time, astronomy and making many, many lists…
Hopefully this isn’t too zombified yet…
I just added the iFart app. I had $0.99 worth of fun with it in the first 3 minutes. 
There’s a cool app called Sol that tells you when sunrise and sunset are.
Hypothetically, if this were, say, my iPhone application, I would never think to post such blatant spam about it on the SDMB. Nope. Not a chance.
Buy 10 copies and tell your friends.

Does anyone use a third party app for mms. I have heard of swirlyMMS but cant find it on the apps store.
Declan
ah thats probably why

Does it do many different versions of solitaire? I’m kind of addicted to the Chinese variation of Klondike right now.
Do any iphone solitaires offer multiple versions with undo capability?
This is kinda making me put off getting one right now, believe it or not.
