After searching through the thread, I think I've confirmed my suspicions that this is confined to my phone, but I thought I'd ask anyway in case.
Is anyone else having trouble with SMS / 3G? Every so often, I'll find that texts aren't coming in. I'll send a text in the middle of a conversation and there won't be a reply (which is unusual for a conversation). Then I'll send a text to Google to check whether or not my texts are working (since Google's texting service is automated and immediate, I know that if I don't get a reply, the problem's on my end). Once I don't get a reply, I'll toggle airplane mode or reboot the phone, and after a few minutes, the missing texts will come in.
Is this a problem with the hardware or could it be software related? I'm running Jerry's latest ROM with the latest Green Recovery.
