Check some reviews from the UK on the 735. Those reviews helped me make up my mind. I would definitely choose the 735/730 over the 640 any day, though I would prefer an IPS display over the OLED on the 735.I have read all the reviews on the older 735 and they didnt sound too bad. I didnt know if there were any improvements on the new version other than the 16gb instead of 8. I dont believe verizon has the 640. Its surprises me this phone has been out a week and still no reviews on the verizon site.
Does anyone know about the differences between the Lumia 735 that the Microsoft Store is offering for Verizon and the Lumia 735 that Verizon is selling? Both appear to have 16GB of internal memory. Verizon is selling theirs for a few dollars less.
