Ok... maybe forbidden by Apple, but assuming this is permitted. What would be the best way to get the current location (not difficult) and posting it to a web service (also not much of a challenge). The app is for an artist who wants people to see where he is at the moment. Personally, I wouldn't want people to know where I am 24/7 but that's performance art I guess. An exact location is not wanted but a town or area would be preferred. I could modify the string when it gets to the server and make it more vague by rounding the LOG and LAT.
The app the fans would use would retrieve his current location from the server and update the map view with a location.
I suppose one way would be for him to find out his coordinates and post that to a web page but I'd like it to update automatically.
A response with code is not necessary, just a general opinion on methodology/advisability would be appreciated
I would probably give him a webpage to go to that records his position every time he visits. It would be a private URL, and perhaps use some lightweight authentication. For versatility, I'd record the exact position in the database (in case he changes his mind on how it should work later on). However, you could use an external service or another purchased database with zips or city information with lat/lng data, so you could just provide users of the client app with his general vicinity rather than exact location.
The alternative would be to give him an ad hoc app that does the same thing, but putting together that location recording webpage would be a much simpler process. Could be handy for other things, too.
Here's a little writeup about getting location from mobile Safari, just as a reference: http://mobiforge.com/developing/story/location-iphone-web-apps
Why wouldn't you just use google latitude and read out his status?
I think this should really be done as a web page web-app. You can get coordinates from the device through mobile safari and you can skip the app approval process. You can also set it up so it runs fullscreen on his phone and he won't know the difference. You can also put a password on it.
There is a good chance it would not get approved as a regular app.
You can always meta refresh the page to keep it updating.

"Artist" must log in to his application (thus insuring that he want to share his coordinates with your webserver), then you use CLLocationManager to get his coordinates and make a reverse geocoding using Google Maps API to get country and city for given coordinates.
Can't see anything special about it :)

I am in the process of building an app, for the record I am using the code from the ECSlidingView controller. I would like for my app to use the GPS to pull data from my web interface letting the user know that they can do certain things at a given location. So for example, I have a user go to a store and lets say I want them to make a payment at that location, it will given them that option. Or if the store doesn't offer payment through the app, I disable that. What would be a good way to go about this?
You could try using CoreLocation but you might have trouble getting accurate location inside (it will most probably use wifi or cellular info so the accuracy might not be what you expect). Then, when you get the location, issue a request to your service passing latitude and longiude you receive from CoreLocation. There, you should search by location to retrieve possible matches - consider returning muliple store infos for nearby stores due to the accuracy issues.
I want to make an application on iPhone which locates the mobile number region(area) when the user gets a call. Can anybody give me guideline how to accomplish that task?
You can't access the details of an incoming call on the iPhone.
Crazy idea: User would define a phone number of your server (SIP, VOIP) as "forward when declined"-number. When the user gets a call, he would simply decline it, so it would be forwarded to your server. There you could extract the information and send it to the iPhone (Push Service). And finally you would redirect the call back from the server to the user's iPhone.
For anyone looking for an answer to the second part of this question (how to get the location for a number), there is a similar question (asked interestingly enough one day before this one) with several answers here:
Telephone area code to city name on iOS
I also discovered an SQLite database named calldata.db in the private framework AppSupport.framework that contains US cities, states and area codes, as well as prefixes (the three digits that come after the area code).
Using a query like this you could find out that area code 212 is New York, NY:
SELECT * FROM citycode, npanxx, npa
WHERE npanxx.npa = 212
AND citycode.code = npanxx.rate_center
AND npanxx.npa = npa.npa
I don't however know if accessing/packaging this database would violate any agreements with Apple (I do know that the Default.phoneformat file from AppSupport.framework has been packed with several apps which had no problems getting into the App Store, see comments here: https://stackoverflow.com/a/13116227/381233). Perhaps there are some methods in the AppSupport.framework that would get this information more easily, but that would definitely not be allowed in the app store.
As for the other part of this question (access the details of an incoming call), this would most likely be possible on a jailbroken phone. No doubt there's already a tweak in Cydia that does this.
I'm trying to create functionality in my app that would allow me to release news updates (Via a server) to those using the app, similar to what is found in Doodle Jump:

Any sample code or ideas would be helpful.
You'll probably need to create an API/web service that your app calls on launch (or when entering foreground)...you could populate that with a database that just gives the entries since the last sync...or just returns some response that you've set up. The response should be JSON or XML formatted (I vote JSON) and then in your app, you call it, parse the response, and place/manipulate it however necessary

There are a lot of options here. In any case you will need a web server that hosts these news postings. The route that I would take is some kind of blog site, where you can easily manage posts. Then upon launching the app you make a web service call to said blog and get the news posts. You will need to keep track locally of which posts were read by the user in order to keep the badge count correct.
You could also roll your own server, but I don't really see the point for something so simple.
Another option is a web-service such as Parse
This question is too vague for code samples as we would be essentially writing the entire solution for you in order for it to make sense.
If you have further questions into how to leverage these web services, how to load the feed, how to display it etc... Break it up across multiple questions.
There's a service doing this called Converser, if you're still looking.
Basically I want to send gps coordinates (displayed on a map in the iPhone) from the iPhone to a webserver that store the values in a database. You should then be able to retrieve these coordinates and display them on a web page.
I am thinking of a set up like this:
I want the browser to request and receive the coordinates in real time (every 10 seconds or so) and I'm wondering if this is a good way to mirror the map in a browser or should I use a different approach? Finally, can you see any obvious flaw/flaws in this design (i.e. performance issues)?
your setup makes sense. The question is, what will you use to keep the map in the browser up to date? I would suggest you check out http://socket.io, I think it will do exactly what you need.

Generally speaking, how does an app like "Around Me" acquire the information it displays?
For example: the restaurants that show up in a list that are near me with the address and distance (I think I get the distance piece) where is this information extracted from? Is it Google or something?
I'm not asking how to implement this (that's over my head!) just get an idea of how it occurs.
Thanks StackOverFlow people.
I haven't seen that specific app, but most such apps either have an embedded database of locations or they dynamically query a server back-end (e.g. using HTTP) to fetch a set of locations near you. They know where you are because the app has access to location services to find out your geographic location.
The iPhone has a GPS unit which gives you your latitude and longitude, which it then sends to a backend server (Say Google Maps) and queries it for, in your case a restaurant. The server responds with a set of locations around you.
