So I just switched from a Blackberry over to the I1 last week. Since the switch I have had nothing but problems with texting on this phone. The issue is I will not recieve texts or emails for hours at a time. When I turn the phone off, then back on they all come through. I have a delivery confermation set on my texting and it showed that what I send is delivered, I just don't recieve the repley's. It seems to be particularly bad during the evening and night time hours....which is when I need it most as I work the night shift on my local PD. Nextel/Sprint hasn't been able to help at all with this, and I am honestly at my whit's end with this thing. I am about to switch back to the Blackberry, which I can't stand either....but at least it works.
