Pretty recent development here. A few days ago, for only a couple hours (between 8:30 and 10pm) none of the texts I sent out were delivered, and the ones that were sent to me never made it to me. Well, that isn't true, they came in all at once after 10pm. It did it again last night, between 9 and 11pm, same thing. And just now, it did the same exact thing. This all started the day after my 30 day return period. My bill is current, so it's not a drop of service (obviously) and I have full 3G signal while all this is happening so it's not an issue of no signal. I've found a reset fixes it, and I'm using Handcent SMS. Anybody having similar problems, or have an idea for a fix or anything?
