IPhone GData Unsupported browser?

Question

I'm developing an application that uses the GData API to get documents from google docs.
I tested it all the times with my own google account. That worked perfectly. But now i created a new test account. With this new account I cant get any document. It always just downloads a file that tells me i have an incompatible browser.
The same documents are working perfectly on my own account. Anyone an idea? Are there some settings in my google account for that problem? Can I change something at the NSURConnection? Anyone else with a similar problem?
Btw. with the iPhone Web GUI I can watch the documents without any problems.
Code to download the document:
NSURLRequest *request = [service requestForURL:url ETag:nil httpMethod:nil];
NSURLResponse *response = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&error];
if (error != nil) {
NSLog(@"Error retrieving file: %@", error);
} else {
BOOL written = [data writeToFile:path
options:NSAtomicWrite
error:&error];
if (!written) {
NSLog(@"Error saving file: %@", error);
}

After issuing the command:
config network web-auth captive-bypass enable
The iOS devices can on board. The registration page does not pop up now. It requires you to open a web browser and it appears that chrome for IOS will not work as it still gives an unsupported error but if you open in safari, which I never use, it does work.
