I'm fairly good with the phone not dying... I've also got chargers everywhere, including home, truck, and the local bar, yes, they have a phone charger for me... Lol
Turns out its actually a SEMI tethered jailbreak, so if it dies, I can reboot with limited functionality, essentially no jailbreak stuff, and no email... Phone and text work though... So I'm going to be doing this here in the next couple hours...
