At the moment I am working on a project called blobDrop.

blobDrop is a realtime photo & video gallery available on iPhone, online or locally on a multitouch device.

blobDrop is a realtime installation. New content is synchronized on every running instance.

Users can participate online by uploading footage or by recording a video. This can also be done locally on a central Multi-Touch device or with an iPhone app.

Take a snapshot – Participate and share impression.

blobDrop iPhone App preview:

The following code returns the latitude and longitude of a GPS enabled iPhone:

#import "locationTestAppDelegate.h"
#import 

@implementation locationTestAppDelegate

@synthesize window;
@synthesize locationManager;

- (void)applicationDidFinishLaunching:(UIApplication *)application {    

    [window makeKeyAndVisible];

	locationManager = [[CLLocationManager alloc] init];

}

- (void)dealloc {
    [window release];
    [super dealloc];
}

-(id) init {
	NSLog(@"GPS");
    if (self = [super init]) {
        currentLocation = [[CLLocation alloc] init];
        locationManager = [[CLLocationManager alloc] init];
        locationManager.delegate = self;
        [self start];
    }
    return self;
}

-(void) start {
	NSLog(@"START SEARCHING...");
    [locationManager startUpdatingLocation];
}
-(void) stop {
	NSLog(@"STOP SEARCHING.");
    [locationManager stopUpdatingLocation];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {

	if ( abs([newLocation.timestamp timeIntervalSinceDate: [NSDate date]]) < 120) {
        currentLocation = newLocation;
		NSString *GPSPosition = [NSString stringWithFormat:@"lat=%f&lng=%f", currentLocation.coordinate.latitude, currentLocation.coordinate.longitude ];

		NSLog(@"FOUND YOU: ");
		NSLog(GPSPosition);

		UIAlertView *alert;
		alert = [[UIAlertView alloc] initWithTitle:@"GPS Location:" message:GPSPosition delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
		[alert show];
		[alert release];
	}
}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
	NSLog(@"locationManager ERROR");
    UIAlertView *alert;
    alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[error description] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
    [alert release];
}
