I am thinking of switching carriers from Verizon to AT&T next week when my contract expires. Verizon dropping the Icon has made me concerned about future WP devices that will be available. I'm not interested in the 730/735. Are there any other switchers out there? I'd like to know if apps open/close faster on the 1520 than they do on my 928. I'm starting to wonder if I am actually getting fed up with the OS and not just my 928. Apps like Flipboard and Facebook take several seconds to open and close, and when I unlock my phone, seeing Resuming and having to wait for that is starting to get on my nerves. Should I expect different/better performance in this regard on a 1520? My other concern is that AT&T has far less coverage in Nebraska than Verizon does. I guess as long as I stay east of Lincoln I should be okay. The AT&T reps have just told me that if I hate the coverage in the first 2 weeks to return everything and cancel the service at no charge. It's nice to have that option.
