Google Reader Token Request giving 403 error - iphone

Question

I am trying to get the token from google reader for my iPhone project. I am able to get the Authorization but when I request for the token, I get a 403 Forbidden
Below is my code implementation. Any help would be appreciated.
//The tokenStorer contains the Authorization key
NSString *tokenStorer = [[NSUserDefaults standardUserDefaults]valueForKey:#"authKey"];
NSLog(#"%#", tokenStorer);
NSDictionary *cookieDictionary = [NSDictionary dictionaryWithObjectsAndKeys:#"www.google.com", #"Host",
#"iReader", #"User-Agent",
#"gzip, deflate", #"Accept-Encoding",
tokenStorer, #"Authorization",
nil
];
//#"Auth", NSHTTPCookieName, tokenStorer, NSHTTPCookieValue, #"./google.com", NSHTTPCookieDomain, #"/", NSHTTPCookiePath, nil];
//NSHTTPCookie *authCookie = [NSHTTPCookie cookieWithProperties:cookieDictionary];
//Google token url "http://www.google.com/reader/api/0/token?client=clientName"
NSURL *url=[[NSURL alloc] initWithString:GOOGLE_READER_TOKEN_URL];
NSMutableURLRequest *urlRequest = [[NSMutableURLRequest alloc]initWithURL:url];
[urlRequest setHTTPMethod:#"GET"];
[urlRequest setAllHTTPHeaderFields:cookieDictionary];
NSData *reciveData;
NSURLResponse *response;
NSError *error;
reciveData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error];
NSMutableURLRequest *tokenRequest= [[NSMutableURLRequest alloc] initWithURL:url];
NSString *trial = [[NSString alloc]initWithData:reciveData encoding:NSASCIIStringEncoding];
NSLog(#"%# %d",trial, response);
[url release];

The below code solved my problem:
-(id)queryLoginDetails {
//authKey returns the authorization key
NSString *tokenStorer = [[NSUserDefaults standardUserDefaults]valueForKey:#"authKey"];
NSLog(#"%#", tokenStorer);
NSString *auth = [[NSString alloc] initWithString:
[NSString stringWithFormat:#"GoogleLogin auth=%#", [tokenStorer substringToIndex:[tokenStorer length]-1]]];
NSDictionary *createHeader = [[NSDictionary dictionaryWithObjectsAndKeys:#"www.google.com", #"Host", #"iReader", #"User-Agent", #"gzip, deflate", #"Accept-Encoding", auth, #"Authorization", nil]retain];
NSURL *url =[NSURL URLWithString:GOOGLE_READER_TOKEN_URL];
NSData *recieveData;
NSMutableURLRequest *urlRequest = [[NSMutableURLRequest alloc]initWithURL:url];
[urlRequest setHTTPMethod:#"GET"];
[urlRequest setAllHTTPHeaderFields:createHeader];
NSURLResponse *response;
NSError *error;
recieveData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error];
NSString *myString = [[NSString alloc]initWithData:recieveData encoding:NSASCIIStringEncoding];
return myString;
}
