Not long after Verizonâ€™s confirmation that it would not carry Windows Phone 7 devices this year earlier today, Senior Product Manager Greg Sullivan has confirmed to CNET that Windows Phone 7 is currently GSM-only until the first half of next year due to hardware development timeframe constraints and the compressed launch timeframe for Windows Phone 7 leading to the selection of GSM as the standard of choice due to its ubiquity, while confirming that CDMA-based Windows Phone 7 devices would be available next year.
The relevant quotes from Sullivan follow below with Sullivan also confirming that the decision to omit CDMA support was known internally while reluctant to make public confirmations until Verizonâ€™s comments earlier today:
"For the worldwide market, the vast majority of phones are GSM phones, so we focused on GSM first and then plan to deliver an update that will have great CDMA support in the first half of 2011," "That’s device availability in the first half and we’re very confident of that. That’s probably a conservative estimate." "We had to make some trade-offs, even Microsoft doesn’t have unlimited resources. We had to prioritize doing fewer things, really, really well."
Because of the compressed development timeframe for both the hardware and software other concessions were made as well to ensure that Windows Phone 7 would meet launch targets, such as the initial omission of cut/copy/paste functionality as well as the aforementioned CDMA support.
