There's an issue with incoming SMS/text messages for Cingular Blue/Pre-Merger/Old AT&T customers. Incoming SMS can be delayed for up to 2 hours, so if you've been trying to text me and don't get an immediate response back, that's probably why.
I've already contacted Cingular about this and have a ticket open on the issue.
I'm prob going to call them again tonight (yea for having a foundation account w/access to Business Care) and check the status of it.
In the interim period, send an IM to [RAPP81 Mobile] as my AIM client runs on GPRS/EDGE internet versus SMS, if you need to mobile message me.
BTW, I'm probably going to get 20 messages shotgunned to my phone because I had mobile alerts turned on for MySpace and I had 20 friend add requests in the last hour from some annoying, whorey bot :(
