'Registration failure. Press ok for options. Your PCS Vision username and/or password may be incorrect. Please try again.' This will come up multiple times at my house or wherever there is sketchy signal. I called Sprint's ATS and they had me reset my phone saying it would more than likely fix the problem. Nope! Once the "Data Call Failure" pops up, I can't use email or web even when I'm in a place that shows strong signal. The only way I can fix this is by rebooting my phone each time and that's not something I'm wanting to do every time I loose signal.. Any fixes for this problem? I talked to one of the Sprint guys at their store and they said something about a patch coming out for it soon? Who knows. Thanks Taylor L.
