What's up with Sprint?  Back in June, 2010, I switched over to
Sprint from AT&T because I couldn't tolerate AT&T's subpar call
and data performance (largely due to the iPhone 3G/3GS). The
first year of service on Sprint was better than I experienced on
AT&T - I could actually sustain phone calls and data over EVDO
and WiMax worked.  Then the problems began.  I thought it was my
Evo so I upgraded to the Samsung Galaxy S II Sprint Epic 4G
Touch. Loved the device, but the service had noticeably
deteriorated to the point where even checking in on Foursquare
wasn't possible. Data struggled so much that my battery would
often deplete in 5 hours of standby mode. There were evenings
where I would leave around 10PM with a fully charged battery,
use my phone for maybe a cumulative time of 20-30 minutes, and
it would be dead by 2am. Seriously??  I've since moved on to
T-Mobile's $30 web-only plan and have loved the service here in
Chicago. I've been on it since late February, 2012 and it's
worked extremely well. So, wha
