Any other Sprint users having problems receiving text messages? I haven't been able to get any texts from one specific number for 6 days now. After 3 days I got 25 old texts from my friend that he had sent on those days, but it's still not working. I went to a Sprint store and they told me it's a network problem since they're updating it for the iPhone and that I should just wait until it's fixed. Is anyone else having this problem?
