While a few lucky Sprint customers have already gotten their hands on the new Treo 600, over at TreoCentral a few people are reporting that T-Mobile has delayed the launch of their version of the Treo 600 until Novemeber 24th, which coincidentally (or not) is the first day that cellphone number portability goes into effect. Some are saying it’s because T-Mobile wasn’t happy with the software on the phone, others are saying that Handspring requested the delay after some problems cellphone carrier Orange experienced with the phone in Britain.
