Apple issued a software update for the latest iPhone to help fix connection problems that led to a flurry of online complaints from customers, a Reuters report said.
The Reuters report further quoted T-Mobile, owned by Deutsche Telekom, saying that the software was available for users to download to their iPhones, but that it was not yet clear if the upgrade would fix all the connection problems.
'We have had complaints about connectivity in the Netherlands but have not had more complaints than usual for a 3G phone in Germany. Our technicians said today Apple has issued a software update but it is too early to tell if the problems are solved,' a T-Mobile spokesman said.
AT&T, the only US network operator carrying the iPhone, confirmed that Apple had provided a software update but declined to give details about what it was aimed at fixing.
Apple, which sold about a million iPhones around the launch weekend in July, was not immediately available for comment.
Credit Suisse said in a note that iPhone sales could exceed 2 million units in the US in the third quarter, which is roughly twice the sales of the iPhone's version 1.0, the initial release last year.
That would be consistent with AT&T comments, Credit Suisse added.
Users around the world have complained about dropped calls and inconsistent internet speeds, with the phone often reverting to a slower technology known as Edge even in 3G areas.
