I've had my Tunderbolt for about 3 months now. There was an issue with the stock messaging app sending texts to the wrong people (which is hilariously awful; good job android), but switching to a third party app (handcent) seemed to work. However; today my phone just seemed to stop receiving texts. Not until I reset my phone and cleared my cache did it work again (but still hasn't received the texts from the downtime.) Is this caused by anything in particular? Was clearing my cache/restarting just a quick fix? I'd rather know why this happened, as it is an undetectable problem until it's too late.
